A vulnerability has been identified in COMOS V10.2 (All versions only if web components are used), COMOS V10.3 (All versions < V10.3.3.3 only if web components are used), COMOS V10.3 (All versions >= V10.3.3.3 only if web components are used), COMOS V10.4 (All versions < V10.4.1 only if web components are used). The COMOS Web component of COMOS unpacks specially crafted archive files to relative paths. This vulnerability could allow an attacker to store files in any folder accessible by the COMOS Web webservice. Se ha identificado una vulnerabilidad en COMOS V10.2 (Todas las versiones sólo si se utilizan componentes web), COMOS V10.3 (Todas las versiones anteriores a V10.3.3 sólo si se utilizan componentes web), COMOS V10.3 (Todas las versiones posteriores o iguales a V10.3.3 sólo si se utilizan componentes web), COMOS V10.4 (Todas las versiones anteriores a V10.4.1 sólo si se utilizan componentes web).

CVSS: 9.0EPSS: 97%CPEs: 96EXPL: 4CVE-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') •
CVSS: 10.0EPSS: 96%CPEs: 398EXPL: 30CVE-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') •

https://notcve.org/view.php?id=CVE-2021-32944
A use-after-free issue exists in the DGN file-reading procedure in the Drawings SDK (All versions prior to 2022.4) resulting from the lack of proper validation of user-supplied data. This can result in a memory corruption or arbitrary code execution, allowing attackers to cause a denial-of-service condition or execute code in the context of the current process. Se presenta un problema de uso de la memoria previamente liberada en el procedimiento de lectura de archivos DGN en Drawings SDK (todas las versiones anteriores a 2022.4) resultando en una falta de comprobación apropiada de los datos suministrados por el usuario. Esto puede resultar en una corrupción de memoria o en una ejecución de código arbitrario, permitiendo a atacantes causar una condición de denegación de servicio o ejecutar código en el contexto del proceso actual This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DGN files. • https://cert-portal.siemens.com/productcert/pdf/ssa-155599.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-365397.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-159-02 https://www.zerodayinitiative.com/advisories/ZDI-21-987 https://www.zerodayinitiative.com/advisories/ZDI-21-990 • CWE-416: Use After Free •
