A vulnerability has been identified in SIMATIC STEP 7 (TIA Portal) V15 (All versions), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 5), SIMATIC STEP 7 (TIA Portal) V17 (All versions < V17 Update 2). An attacker could achieve privilege escalation on the web server of certain devices due to improper access control vulnerability in the engineering system software. The attacker needs to have direct access to the impacted web server. Se ha identificado una vulnerabilidad en SIMATIC STEP 7 (TIA Portal) versión V15 (Todas las versiones), SIMATIC STEP 7 (TIA Portal) versión V16 (todas las versiones anteriores a versión V16 Update 5), SIMATIC STEP 7 (TIA Portal) versión V17 (todas las versiones anteriores a versión V17 Update 2). Un atacante podría lograr una escalada de privilegios en el servidor web de determinados dispositivos debido a una vulnerabilidad de control de acceso inapropiada en el software del sistema de ingeniería. • https://cert-portal.siemens.com/productcert/pdf/ssa-350757.pdf • CWE-284: Improper Access Control •
CVSS: 5.9EPSS: 0%CPEs: 205EXPL: 0CVE-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 •
