CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to overwrite arbitrary files.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated SSLVPN user can inject a path traversal sequence to make any directory on the SMA appliance writable.


3) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2025-32821)

CWE-ID: CWE-88 - Argument Injection or Modification

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
