CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2023-31102 – 7-Zip 7Z File Parsing Integer Underflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2023-31102
Ppmd7.c in 7-Zip before 23.00 allows an integer underflow and invalid read operation via a crafted 7Z archive. 7-Zip hasta 22.01 en Linux permite un desbordamiento de números enteros y la ejecución de código a través de un archivo 7Z manipulado. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. 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 7Z files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://ds-security.com/post/integer-overflow-in-7-zip-cve-2023-31102 https://security.netapp.com/advisory/ntap-20231110-0007 https://sourceforge.net/p/sevenzip/discussion/45797/thread/713c8a8269 https://www.7-zip.org/download.html https://www.zerodayinitiative.com/advisories/ZDI-23-1165 • CWE-191: Integer Underflow (Wrap or Wraparound) •

7-Zip through 21.07 on Windows allows privilege escalation and command execution when a file with the .7z extension is dragged to the Help>Contents area. This is caused by misconfiguration of 7z.dll and a heap overflow. The command runs in a child process under the 7zFM.exe process. NOTE: multiple third parties have reported that no privilege escalation can occur **EN DISPUTA** 7-Zip hasta la versión 21.07 en Windows permite la escalada de privilegios y la ejecución de comandos cuando se arrastra un archivo con la extensión .7z al área de Ayuda>Contenido. Esto es causado por una mala configuración de 7z.dll y un desbordamiento de la pila. • https://github.com/kagancapar/CVE-2022-29072 https://github.com/tiktb8/CVE-2022-29072 https://github.com/sentinelblue/CVE-2022-29072 https://github.com/rasan2001/CVE-2022-29072 http://packetstormsecurity.com/files/166763/7-Zip-21.07-Code-Execution-Privilege-Escalation.html https://news.ycombinator.com/item?id=31070256 https://sourceforge.net/p/sevenzip/bugs/2337 https://www.youtube.com/watch?v=sT1cvbu7ZTA • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive. La lógica incorrecta de objetos de descodificador RAR en 7-Zip 18.03 y anteriores puede conducir al uso de memoria no inicializada, lo que permite que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) o ejecuten código arbitrario mediante un archivo RAR manipulado. • http://www.securityfocus.com/bid/104132 http://www.securitytracker.com/id/1040832 https://landave.io/2018/05/7-zip-from-uninitialized-memory-to-remote-code-execution https://sourceforge.net/p/sevenzip/discussion/45797/thread/adc65bfa • CWE-665: Improper Initialization CWE-908: Use of Uninitialized Resource •

7-Zip through 18.01 on Windows implements the "Large memory pages" option by calling the LsaAddAccountRights function to add the SeLockMemoryPrivilege privilege to the user's account, which makes it easier for attackers to bypass intended access restrictions by using this privilege in the context of a sandboxed process. Note: This has been disputed by 3rd parties who argue this is a valid feature of Windows. 7-Zip, hasta la versión 18.01 en Windows, implementa la opción "Large memory pages" llamando a la función LsaAddAccountRights para añadir el privilegio SeLockMemoryPrivilege a la cuenta de usuario, lo que facilita que atacantes omitan las restricciones de acceso planeadas mediante el uso de este privilegio en el contexto de un proceso en sandbox. • https://sourceforge.net/p/sevenzip/discussion/45797/thread/e730c709/?limit=25&page=1#b240 • CWE-269: Improper Privilege Management •

Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, allows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive. Una gestión insuficiente de excepciones en el método NCompress::NRar3::CDecoder::Code en 7-Zip, en versiones anteriores a la 18.00, y en p7zip puede conducir a múltiples corrupciones de memoria en el código PPMd, permitir que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) o ejecutar código arbitrario mediante un archivo RAR manipulado. • http://www.securitytracker.com/id/1040831 https://0patch.blogspot.si/2018/02/two-interesting-micropatches-for-7-zip.html https://landave.io/2018/01/7-zip-multiple-memory-corruptions-via-rar-and-zip • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
