CVE-2021-45105 – Apache Log4j2 does not always protect from infinite recursion in lookup evaluation
https://notcve.org/view.php?id=CVE-2021-45105
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. Apache Log4j2 versiones 2.0-alpha1 hasta 2.16.0 (excluyendo las versiones 2.12.3 y 2.3.1) no protegían de la recursión no controlada de las búsquedas autorreferenciales. Esto permite a un atacante con control sobre los datos de Thread Context Map causar una denegación de servicio cuando es interpretada una cadena diseñada. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45105 https://github.com/pravin-pp/log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105-1 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-dileepdkumar-https-github.com-pravin-pp-log4j2-CVE-2021-45105-v htt • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
