A vulnerability has been identified in SIMATIC WinCC OA V3.14 and prior (All versions < V3.14-P021). Improper access control to a data point of the affected product could allow an unauthenticated remote user to escalate its privileges in the context of SIMATIC WinCC OA V3.14. This vulnerability could be exploited by an attacker with network access to port 5678/TCP of the SIMATIC WinCC OA V3.14 server. Successful exploitation requires no user privileges and no user interaction. This vulnerability could allow an attacker to compromise integrity and availability of the SIMATIC WinCC OA system. • http://www.securityfocus.com/bid/105332 https://cert-portal.siemens.com/productcert/pdf/ssa-346256.pdf • CWE-269: Improper Privilege Management •

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Las implementaciones de (1) TLS y (2) DTLS en OpenSSL 1.0.1 en versiones anteriores a 1.0.1g no manejan adecuadamente paquetes Heartbeat Extension, lo que permite a atacantes remotos obtener información sensible desde la memoria de proceso a través de paquetes manipulados que desencadenan una sobrelectura del buffer, según lo demostrado mediante la lectura de claves privadas, relacionado con d1_both.c y t1_lib.c, también conocido como bug Heartbleed. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. • https://www.exploit-db.com/exploits/32764 https://www.exploit-db.com/exploits/32791 https://www.exploit-db.com/exploits/32998 https://www.exploit-db.com/exploits/32745 https://github.com/0x90/CVE-2014-0160 https://github.com/jdauphant/patch-openssl-CVE-2014-0160 https://github.com/caiqiqi/OpenSSL-HeartBleed-CVE-2014-0160-PoC https://github.com/obayesshelton/CVE-2014-0160-Scanner https://github.com/MrE-Fog/CVE-2014-0160-Chrome-Plugin https://github.com/Xyl2k/CVE-2014&# • CWE-125: Out-of-bounds Read CWE-201: Insertion of Sensitive Information Into Sent Data •

Siemens SIMATIC WinCC OA before 3.12 P002 January uses a weak hash algorithm for passwords, which makes it easier for remote attackers to obtain access via a brute-force attack. Siemens SIMATIC WinCC OA anterior a 3.12 P002 January usa un algoritmo hash débil para las contraseñas, lo que hace más fácil para atacantes remotos obtener acceso a través de un ataque de fuerza bruta. • http://ics-cert.us-cert.gov/advisories/ICSA-14-035-01 http://osvdb.org/102809 http://www.siemens.com/innovation/pool/de/forschungsfelder/siemens_security_advisory_ssa-342587.pdf https://exchange.xforce.ibmcloud.com/vulnerabilities/90934 • CWE-310: Cryptographic Issues •
