CVE-2021-40358

https://notcve.org/view.php?id=CVE-2021-40358

A vulnerability has been identified in SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC04), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1), SIMATIC WinCC V15 and earlier (All versions < V15 SP1 Update 7), SIMATIC WinCC V16 (All versions < V16 Update 5), SIMATIC WinCC V17 (All versions < V17 Update 2), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 5). Legitimate file operations on the web server of the affected systems do not properly neutralize special elements within the pathname. An attacker could then cause the pathname to resolve to a location outside of the restricted directory on the server and read, write or delete unexpected critical files. Se ha identificado una vulnerabilidad en SIMATIC PCS 7 V8.2 (Todas las versiones), SIMATIC PCS 7 V9.0 (Todas las versiones anteriores a V9.0 SP3 UC04), SIMATIC PCS 7 V9.1 (Todas las versiones anteriores a V9. 1 SP1), SIMATIC WinCC V15 y anteriores (Todas las versiones anteriores a V15 SP1 Update 7), SIMATIC WinCC V16 (Todas las versiones anteriores a V16 Update 5), SIMATIC WinCC V17 (Todas las versiones anteriores a V17 Update 2), SIMATIC WinCC V7.4 (Todas las versiones anteriores a V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (Todas las versiones anteriores a V7.5 SP2 Update 5). Las operaciones de archivo legítimas en el servidor web de los sistemas afectados no neutralizan correctamente los elementos especiales dentro de la ruta de acceso. • https://cert-portal.siemens.com/productcert/pdf/ssa-840188.pdf • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

CVE-2021-3449 – NULL pointer deref in signature_algorithms processing

https://notcve.org/view.php?id=CVE-2021-3449

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. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •
