CVE-2021-45046 – Apache Log4j2 Deserialization of Untrusted Data Vulnerability
https://notcve.org/view.php?id=CVE-2021-45046
It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default. Se descubrió que la corrección para abordar CVE-2021-44228 en Apache Log4j versiones 2.15.0 estaba incompleta en ciertas configuraciones no predeterminadas. Esto podría permitir a los atacantes con control sobre los datos de entrada de Thread Context Map (MDC) cuando la configuración de registro utiliza un Pattern Layout no predeterminado con un Context Lookup (por ejemplo, $${ctx:loginId}) o un Thread Context Map pattern (%X, %mdc, o %MDC) para elaborar datos de entrada maliciosos utilizando un patrón JNDI Lookup que resulta en una fuga de información y ejecución de código remoto en algunos entornos y ejecución de código local en todos los entornos. • https://github.com/BobTheShoplifter/CVE-2021-45046-Info https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45046 https://github.com/pravin-pp/log4j2-CVE-2021-45046 http://www.openwall.com/lists/oss-security/2021/12/14/4 http://www.openwall.com/lists/oss-security/2021/12/15/3 http://www.openwall.com/lists/oss-security/2021/12/18/1 https://cert-portal.siemen • CWE-400: Uncontrolled Resource Consumption CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
CVE-2021-44228 – Apache Log4j2 Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44228
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. • https://github.com/fullhunt/log4j-scan https://github.com/Puliczek/CVE-2021-44228-PoC-log4j-bypass-words https://github.com/cyberstruggle/L4sh https://github.com/woodpecker-appstore/log4j-payload-generator https://github.com/tangxiaofeng7/apache-log4j-poc https://www.exploit-db.com/exploits/51183 https://www.exploit-db.com/exploits/50592 https://www.exploit-db.com/exploits/50590 https://github.com/logpresso/CVE-2021-44228-Scanner https://github.com/jas502n/Log4j2-CVE-2021-44228 h • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-502: Deserialization of Untrusted Data CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •

A vulnerability has been identified in Opcenter Execution Discrete (All versions < V3.2), Opcenter Execution Foundation (All versions < V3.2), Opcenter Execution Process (All versions < V3.2), Opcenter Intelligence (All versions < V3.3), Opcenter Quality (All versions < V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (All versions < V2.6), SIMATIC IT Production Suite (All versions < V8.0), SIMATIC Notifier Server for Windows (All versions), SIMATIC PCS neo (All versions < V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (All versions < V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 2), SIMOCODE ES V15.1 (All versions < V15.1 Update 4), SIMOCODE ES V16 (All versions < V16 Update 1), Soft Starter ES V15.1 (All versions < V15.1 Update 3), Soft Starter ES V16 (All versions < V16 Update 1). Sending multiple specially crafted packets to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself. On some cases the vulnerability could leak random information from the remote service.
