An arbitrary code execution flaw was found in Foreman. This issue may allow an admin user to execute arbitrary code on the underlying operating system by setting global parameters with a YAML payload.
A command injection flaw was found in foreman. This flaw allows an authenticated user with admin privileges on the foreman instance to transpile commands through CoreOS and Fedora CoreOS configurations in templates, possibly resulting in arbitrary command execution on the underlying operating system.
Brian Bouterse of Red Hat reports:
The Qpid server on Satellite6 does not properly restrict message types that can be sent from managed content hosts. An attacker with administrative access to a managed content host could send arbitrary messages containing pickle() encoded data which would then be processed on the Satellite6 server.
A flaw was found in rubyipmi, a gem used in the Baseboard Management Controller (BMC) component of Red Hat Satellite. An authenticated attacker with host creation or update permissions could exploit this vulnerability by crafting a malicious username for the BMC interface. This could lead to remote code execution (RCE) on the system.
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within .solv files due to insufficient input validation. An attacker can provide a specially crafted .solv file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
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 sensitive information exposure vulnerability was found in foreman. Contents of tomcat's server.xml file, which contain passwords to candlepin's keystore and truststore, were found to be world readable.
A flaw was found in the logback package. When using a specially-crafted configuration, this issue could allow a remote authenticated attacker to execute arbitrary code loaded from LDAP servers.
A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.
A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted .solv file containing negative size values in the repoaddsolv function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
A credential leak vulnerability was found in Red Hat Satellite through Azure Resource Manager. This flaw exposes the compute resources credentials with in the Satellite.
Nokogiri gem 1.5.x and 1.6.x has DoS while parsing XML entities by failing to apply limits
Nokogiri gem 1.5.x has Denial of Service via infinite loop when parsing XML documents
Versions of Foreman as shipped with Red Hat Satellite 6 does not check for a correct CSRF token in the logout action. Therefore, an attacker can log out a user by having them view specially crafted content.
A path traversal vulnerability exists in Ansible when extracting tarballs. An attacker could craft a malicious tarball so that when using the galaxy importer of Ansible Automation Hub, a symlink could be dropped on the disk, resulting in files being overwritten.
The collection remote for pulpansible stores tokens in plaintext instead of using pulp's encrypted field (https://github.com/pulp/pulpansible/blob/main/pulpansible/app/models.py#L234) and exposes them in read/write mode via the API (https://github.com/pulp/pulpansible/blob/main/pulpansible/app/serializers.py#L170) instead of marking it as write only.
A flaw was found in the Katello plugin for Foreman, where it is possible to store malicious JavaScript code in the "Description" field of a user. This code can be executed when opening certain pages, for example, Host Collections.
A flaw has been found in foreman when HTTP parameters are modified in httpproxiescontroller and httpproxy files. Attackers can perform an SSRF attack and steal cloud metadata service on AWS/GCP/Azure environment through foreman component.
