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

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier.

A vulnerability has been identified in Opcenter Execution Foundation (All versions), Opcenter Intelligence (All versions), Opcenter Quality (All versions), Opcenter RDL (All versions), SIMATIC PCS neo V4.0 (All versions), SIMATIC PCS neo V4.1 (All versions), SIMATIC PCS neo V5.0 (All versions < V5.0 Update 1), SINEC NMS (All versions if operated in conjunction with UMC < V2.15), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions), Totally Integrated Automation Portal (TIA Portal) V18 (All versions), Totally Integrated Automation Portal (TIA Portal) V19 (All versions). Affected products contain a heap-based buffer overflow vulnerability in the integrated UMC component. This could allow an unauthenticated remote attacker to execute arbitrary code.

A vulnerability has been identified in SINEC NMS (All versions < V3.0 SP1). The affected application contains a database function, that does not properly restrict the permissions of users to write to the filesystem of the host system. This could allow an authenticated medium-privileged attacker to write arbitrary content to any location in the filesystem of the host system.

A vulnerability has been identified in Opcenter Execution Foundation (All versions), Opcenter Quality (All versions), Opcenter RDL (All versions), SIMATIC PCS neo V4.0 (All versions), SIMATIC PCS neo V4.1 (All versions < V4.1 Update 2), SIMATIC PCS neo V5.0 (All versions < V5.0 Update 1), SINEC NMS (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions < V17 Update 8), Totally Integrated Automation Portal (TIA Portal) V18 (All versions < V18 Update 5), Totally Integrated Automation Portal (TIA Portal) V19 (All versions < V19 Update 3). Affected products contain a heap-based buffer overflow vulnerability in the integrated UMC component. This could allow an unauthenticated remote attacker to execute arbitrary code.

A vulnerability has been identified in SINEC NMS (All versions < V3.0). The affected application does not properly enforce authorization checks. This could allow an authenticated attacker to bypass the checks and modify settings in the application without authorization.

A vulnerability has been identified in SINEC NMS (All versions < V3.0). The affected application does not properly validate user input to a privileged command queue. This could allow an authenticated attacker to execute OS commands with elevated privileges.

A vulnerability has been identified in SINEC NMS (All versions < V3.0). The affected application does not properly enforce authorization checks. This could allow an authenticated attacker to bypass the checks and elevate their privileges on the application.

A vulnerability has been identified in SINEC NMS (All versions < V3.0). The importCertificate function of the SINEC NMS Control web application contains a path traversal vulnerability. This could allow an authenticated attacker it to delete arbitrary certificate files on the drive SINEC NMS is installed on.
