CVSS: 9.8EPSS: 16%CPEs: 1EXPL: 0CVE-2022-36974 – Ivanti Avalanche Web File Server Service Deserialization of Untrusted Data Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-36974
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ivanti Avalanche 6.3.2.3490. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the Web File Server service. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the service account. • https://download.wavelink.com/Files/avalanche_v6.3.4_release_notes.txt https://www.zerodayinitiative.com/advisories/ZDI-22-779 • CWE-502: Deserialization of Untrusted Data •

Ivanti Avalanche (Premise) 6.3.2 allows remote unauthenticated users to read arbitrary files via Absolute Path Traversal. The imageFilePath parameter processed by the /AvalancheWeb/image endpoint is not verified to be within the scope of the image folder, e.g., the attacker can obtain sensitive information via the C:/Windows/system32/config/system.sav value. Ivanti Avalanche (Premise) versión 6.3.2 permite a usuarios remotos no autenticados leer archivos arbitrarios por medio de un Salto de Ruta Absoluto. No es verificado que el parámetro imageFilePath procesado por el endpoint /AvalancheWeb/image esté dentro del ámbito de la carpeta de imágenes, por ejemplo, el atacante puede obtener información confidencial por medio del valor C:/Windows/system32/config/system.sav • https://forums.ivanti.com/s/article/Security-Alert-CVE-2021-30497-Directory-Traversal-Vulnerability?language=en_US https://help.ivanti.com/wl/help/en_us/aod/5.4/Avalanche/Console/Launching_the_Avalanche.htm https://ssd-disclosure.com/ssd-advisory-ivanti-avalanche-directory-traversal • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
