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.

libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP2). The affected application does not properly handle user session establishment and invalidation. This could allow a remote attacker to circumvent the additional multi factor authentication for user session establishment.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). Affected applications do not properly handle log rotation. This could allow an unauthenticated remote attacker to cause a denial of service condition through resource exhaustion on the device.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application allows authenticated, low privilege users with the 'Manage own remote connections' permission to retrieve details about other users and group memberships.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application does not properly implement brute force protection against user credentials in its Client Communication component. This could allow an attacker to learn user credentials that are vulnerable to brute force attacks.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application does not properly implement brute force protection against user credentials in its web API. This could allow an attacker to learn user credentials that are vulnerable to brute force attacks.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application does not properly assign rights to temporary files created during its update process. This could allow an authenticated attacker with the 'Manage firmware updates' role to escalate their privileges on the underlying OS level.
