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') •
CVSS: 9.8EPSS: 4%CPEs: 1EXPL: 0CVE-2021-42132 – Ivanti Avalanche PrinterDeviceServer Service Command Injection Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-42132
A command Injection vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to perform arbitrary command execution. Se presenta una vulnerabilidad de inyección de comandos en Ivanti Avalanche versiones anteriores a 6.3.3, que permite a un atacante con acceso al servicio Inforail llevar a cabo la ejecución de un comando arbitrario This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ivanti Avalanche. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the runAgentRestarter method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. • https://forums.ivanti.com/s/article/Security-Alert-CVE-s-Addressed-in-Avalanche-6-3-3 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
