CVSS: 7.3EPSS: 0%CPEs: 2EXPL: 0CVE-2024-5102 – Elevation of Privelage via symlinked file in Avast Antivirus
https://notcve.org/view.php?id=CVE-2024-5102
A sym-linked file accessed via the repair function in Avast Antivirus <24.2 on Windows may allow user to elevate privilege to delete arbitrary files or run processes as NT AUTHORITY\SYSTEM. The vulnerability exists within the "Repair" (settings -> troubleshooting -> repair) feature, which attempts to delete a file in the current user's AppData directory as NT AUTHORITY\SYSTEM. A low-privileged user can make a pseudo-symlink and a junction folder and point to a file on the system. This can provide a low-privileged user an Elevation of Privilege to win a race-condition which will re-create the system files and make Windows callback to a specially-crafted file which could be used to launch a privileged shell instance. This issue affects Avast Antivirus prior to 24.2. Un archivo con enlace simbólico al que se accede a través de la función de reparación en Avast Antivirus <24.2 en Windows puede permitir al usuario elevar privilegios para eliminar archivos arbitrarios o ejecutar procesos como NT AUTHORITY\SYSTEM. • https://support.norton.com/sp/static/external/tools/security-advisories.html • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-1284: Improper Validation of Specified Quantity in Input •
