A crafted request uri-path can cause modproxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.

When LDAP remote authentication is configured on F5OS, a remote user without an assigned role will be incorrectly authorized.

A directory traversal vulnerability exists in the F5OS QKView utility that allows an authenticated attacker to read files outside the QKView directory.

In F5OS-A version 1.x before 1.1.0 and F5OS-C version 1.x before 1.5.0, excessive file permissions in F5OS allows an authenticated local attacker to execute limited set of commands in a container and impact the F5OS controller.

In F5OS-A version 1.x before 1.1.0 and F5OS-C version 1.x before 1.4.0, a directory traversal vulnerability exists in an undisclosed location of the F5OS CLI that allows an attacker to read arbitrary files.

Improper input validation in UEFI firmware error handler for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

Improper access control in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

Apache HTTP Server could allow a remote attacker to bypass security restrictions, caused by an encoding flaw in modproxy. By sending specially crafted requests with incorrect encoding an attacker could exploit this vulnerability to bypass authentication validation.

Incorrect execution-assigned permissions in the Linux kernel mode driver for the Intel(R) 800 Series Ethernet Driver before version 1.15.4 may allow an authenticated user to potentially enable information disclosure via local access.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.

A potential security vulnerability in some Intel(R) Atom(R) and Intel(R) Xeon(R) Scalable Processors may allow escalation of privilege. Intel is releasing firmware updates to mitigate this potential vulnerability.

When running in appliance mode, an authenticated attacker assigned the Administrator or Resource Administrator role may be able to bypass Appliance mode restrictions utilizing system diagnostics tcpdump command utility on a F5OS-A/C system.

On an F5OS system, if the root user configures the system to allow login using SSH key-based authentication and later enables appliance mode, the system still allows access using SSH key-based authentication. For an attacker to exploit this vulnerability they must obtain possession of a private key corresponding to a previously-configured entry in root's SSH authorizedkeys file.

On F5OS, an improper authorization vulnerability exists where remotely authenticated users (LDAP, RADIUS, TACACS+) may be authorized with higher privilege F5OS roles.

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection. (CVE-2022-4304 )

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the caller, prepends a new BIOfasn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the BIO chain to the caller. Under certain conditions, for example if a CMS recipient public key is invalid, the new filter BIO is freed and the function returns a NULL result indicating a failure. However, in this case, the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal pointers to the previously freed filter BIO. If the caller then goes on to call BIOpop() on the BIO then a use-after-free will occur. This will most likely result in a crash. This scenario occurs directly in the internal function B64writeASN1() which may cause BIOnewNDEF() to be called and will subsequently call BIOpop() on the BIO. This internal function is in turn called by the public API functions PEMwritebioASN1stream, PEMwritebioCMSstream, PEMwritebioPKCS7stream, SMIMEwriteASN1, SMIMEwriteCMS and SMIMEwritePKCS7. Other public API functions that may be impacted by this include i2dASN1biostream, BIOnewCMS, BIOnewPKCS7, i2dCMSbiostream and i2dPKCS7biostream. The OpenSSL cms and smime command line applications are similarly affected.

The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.

Sequence of processor instructions leads to unexpected behavior for some Intel(R) Processors may allow an authenticated user to potentially enable escalation of privilege and/or information disclosure and/or denial of service via local access.

urllib3 is a user-friendly HTTP client library for Python. When using urllib3's proxy support with ProxyManager, the Proxy-Authorization header is only sent to the configured proxy, as expected. However, when sending HTTP requests without using urllib3's proxy support, it's possible to accidentally configure the Proxy-Authorization header even though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn't treat the Proxy-Authorization HTTP header as one carrying authentication material and thus doesn't strip the header on cross-origin redirects. Because this is a highly unlikely scenario, we believe the severity of this vulnerability is low for almost all users. Out of an abundance of caution urllib3 will automatically strip the Proxy-Authorization header during cross-origin redirects to avoid the small chance that users are doing this on accident. Users should use urllib3's proxy support or disable automatic redirects to achieve safe processing of the Proxy-Authorization header, but we still decided to strip the header by default in order to further protect users who aren't using the correct approach. We believe the number of usages affected by this advisory is low. It requires all of the following to be true to be exploited: 1. Setting the Proxy-Authorization header without using urllib3's built-in proxy support. 2. Not disabling HTTP redirects. 3. Either not using an HTTPS origin server or for the proxy or target origin to redirect to a malicious origin. Users are advised to update to either version 1.26.19 or version 2.2.2. Users unable to upgrade may use the Proxy-Authorization header with urllib3's ProxyManager, disable HTTP redirects using redirects=False when sending requests, or not user the Proxy-Authorization header as mitigations.

On F5OS-A beginning in version 1.2.0 to before 1.3.0 and F5OS-C beginning in version 1.3.0 to before 1.5.0, processing F5OS tenant file names may allow for command injection. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

A use after free vulnerability exists in curl <7.87.0. Curl can be asked to tunnel virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in modproxyajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. The nftverdictinit() function allows positive values as drop error within the hook verdict, and hence the nfhookslow() function can cause a double free vulnerability when NFDROP is issued with a drop error which resembles NFACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
