A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected application uses a password hashing implementation with a static, hardcoded salt shared across all users and installations, and is configured with an insufficient number of iterations. This could allow an attacker to efficiently recover user passwords using brute-force or precomputed attacks, potentially resulting in unauthorized access.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected system includes a binary that is configured with the capdacoverride capability. This capability allows the process to bypass file system permission checks, resulting in unrestricted file system access. This could allow a local attacker to escalate privileges leading to arbitrary file modification and gaining root privileges on the system.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The affected application does not properly sanitize path input in the GET /api/sftp/uploadFiles endpoint used for directory listing. This allows path traversal through crafted input, enabling access to unintended file system locations.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The application does not properly sanitize user input in the /api/sftp/uploadFiles endpoint, allowing the injection of shell command payloads via crafted directory names. These payloads are stored and executed when directory listings are retrieved. This could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system with the privileges of the affected service user (sinecins).
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly validate authorization of a user to query the "/api/sftp/users" endpoint. This could allow an authenticated remote attacker to gain knowledge about the list of configured users of the SFTP service and also modify that configuration.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly invalidate sessions when the associated user is deleted or disabled or their permissions are modified. This could allow an authenticated attacker to continue performing malicious actions even after their user account has been disabled.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly restrict the size of generated log files. This could allow an unauthenticated remote attacker to trigger a large amount of logged events to exhaust the system's resources and create a denial of service condition.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly validate input sent to specific endpoints of its web API. This could allow an authenticated remote attacker with high privileges on the application to execute arbitrary code on the underlying OS.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application uses hard-coded cryptographic key material to obfuscate configuration files. This could allow an attacker to learn that cryptographic key material through reverse engineering of the application binary and decrypt arbitrary backup files.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly sanitize user provided paths for SFTP-based file up- and downloads. This could allow an authenticated remote attacker to manipulate arbitrary files on the filesystem and achieve arbitrary code execution on the device.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). Affected software does not correctly validate the response received by an UMC server. An attacker can use this to crash the affected software by providing and configuring a malicious UMC server or by manipulating the traffic from a legitimate UMC server (i.e. leveraging CVE-2023-48427).
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). The REST API of affected devices does not check the length of parameters in certain conditions. This allows a malicious admin to crash the server by sending a crafted request to the API. The server will automatically restart.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). The Web UI of affected devices does not check the length of parameters in certain conditions. This allows a malicious admin to crash the server by sending a crafted request to the server. The server will automatically restart.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). The radius configuration mechanism of affected products does not correctly check uploaded certificates. A malicious admin could upload a crafted certificate resulting in a denial-of-service condition or potentially issue commands on system level.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). Affected products do not properly validate the certificate of the configured UMC server. This could allow an attacker to intercept credentials that are sent to the UMC server as well as to manipulate responses, potentially allowing an attacker to escalate privileges.
HTTP/2 Rapid reset attack The HTTP/2 protocol allows clients to indicate to the server that a previous stream should be canceled by sending a RSTSTREAM frame. The protocol does not require the client and server to coordinate the cancellation in any way, the client may do it unilaterally. The client may also assume that the cancellation will take effect immediately when the server receives the RSTSTREAM frame, before any other data from that TCP connection is processed.
Abuse of this feature is called a Rapid Reset attack because it relies on the ability for an endpoint to send a RSTSTREAM frame immediately after sending a request frame, which makes the other endpoint start working and then rapidly resets the request. The request is canceled, but leaves the HTTP/2 connection open.
The HTTP/2 Rapid Reset attack built on this capability is simple: The client opens a large number of streams at once as in the standard HTTP/2 attack, but rather than waiting for a response to each request stream from the server or proxy, the client cancels each request immediately.
The ability to reset streams immediately allows each connection to have an indefinite number of requests in flight. By explicitly canceling the requests, the attacker never exceeds the limit on the number of concurrent open streams. The number of in-flight requests is no longer dependent on the round-trip time (RTT), but only on the available network bandwidth.
In a typical HTTP/2 server implementation, the server will still have to do significant amounts of work for canceled requests, such as allocating new stream data structures, parsing the query and doing header decompression, and mapping the URL to a resource. For reverse proxy implementations, the request may be proxied to the backend server before the RSTSTREAM frame is processed. The client on the other hand paid almost no costs for sending the requests. This creates an exploitable cost asymmetry between the server and the client.
Multiple software artifacts implementing HTTP/2 are affected. This advisory was originally ingested from the swift-nio-http2 repo advisory and their original conent follows.
swift-nio-http2 specific advisory swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time. This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new Channels to serve the traffic. This can easily overwhelm an EventLoop and prevent it from making forward progress.
swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.
A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 1). An authenticated remote attacker with access to the Web Based Management (443/tcp) of the affected product, could potentially inject commands into the dhcpd configuration of the affected product.

A vulnerability was found in NodeJS due to weak randomness in the WebCrypto keygen within the SecretKeyGenTraits::DoKeyGen() in src/crypto/cryptokeygen.cc. Node.js made calls to EntropySource() in SecretKeyGenTraits::DoKeyGen(). However, it does not check the return value and assumes the EntropySource() always succeeds, but it can and sometimes will fail. This flaw allows a remote attacker to decrypt sensitive information.
A vulnerability was found in NodeJS due to improper validation of HTTP requests. The llhttp parser in the HTTP module in Node.js does not correctly handle header fields that are not terminated with CLRF. This issue may result in HTTP Request Smuggling. This flaw allows a remote attacker to send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf that might be accessible under some circumstances to a non-admin user instead of /etc/ssl as was the case in versions prior to the upgrade to OpenSSL 3.
A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.20.0, <18.5.0 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.
A vulnerability was found in NodeJS due to the llhttp parser in the HTTP module incorrectly handling multi-line Transfer-Encoding headers. This issue can lead to HTTP Request Smuggling (HRS). This flaw allows a remote attacker to send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers, causing web cache poisoning, and conducting XSS attacks.

AES OCB fails to encrypt some bytes
A flaw was found in OpenSSL. The issue in CVE-2022-1292 did not find other places in the crehash script where it possibly passed the file names of certificates being hashed to a command executed through the shell. Some operating systems distribute this script in a manner where it is automatically executed. On these operating systems, this flaw allows an attacker to execute arbitrary commands with the privileges of the script.
A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by the forwarders may be cached and used by name if it needs to recurse for any reason. This issue causes it to obtain and pass on potentially incorrect answers. This flaw allows a remote high privileged attacker to manipulate cache results with incorrect records, leading to queries made to the wrong servers, possibly resulting in false information received on the client's end.
A flaw was found in Bind that incorrectly handles certain crafted TCP streams. The vulnerability allows TCP connection slots to be consumed for an indefinite time frame via a specifically crafted TCP stream sent from a client. This flaw allows a remote attacker to send specially crafted TCP streams with 'keep-response-order' enabled that could cause connections to BIND to remain in CLOSEWAIT status for an indefinite period, even after the client has terminated the connection. This issue results in BIND consuming resources, leading to a denial of service.
OpenSSL could provide weaker than expected security, caused by a carry propagation flaw in the MIPS32 and MIPS64 squaring procedure. An attacker could exploit this vulnerability to launch further attacks on the system
