CVSS: 7.8EPSS: 96%CPEs: 39EXPL: 56CVE-2021-3156 – Sudo Heap-Based Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2021-3156
Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via "sudoedit -s" and a command-line argument that ends with a single backslash character. Sudo versiones anteriores a 1.9.5p2 contiene un error de desbordamiento que puede resultar en un desbordamiento de búfer basado en la pila, lo que permite la escalada de privilegios a root a través de "sudoedit -s" y un argumento de línea de comandos que termina con un solo carácter de barra invertida A flaw was found in sudo. A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is exploitable by any local user who can execute the sudo command (by default, any local user can execute sudo) without authentication. Successful exploitation of this flaw could lead to privilege escalation. • https://www.exploit-db.com/exploits/49521 https://www.exploit-db.com/exploits/49522 https://github.com/blasty/CVE-2021-3156 https://github.com/worawit/CVE-2021-3156 https://github.com/stong/CVE-2021-3156 https://github.com/reverse-ex/CVE-2021-3156 https://github.com/CptGibbon/CVE-2021-3156 https://github.com/Rvn0xsy/CVE-2021-3156-plus https://github.com/mr-r3b00t/CVE-2021-3156 https://github.com/0xdevil/CVE-2021-3156 https://github.com/unauth401/CVE-20 • CWE-122: Heap-based Buffer Overflow CWE-193: Off-by-one Error •
