CVE-2026-85426
MOOS-IvP uMemWatch through 24.8.1 constructs shell commands from attacker-chosen MOOS client names without sanitization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
MOOS-IvP uMemWatch through 24.8.1 constructs shell commands from attacker-chosen MOOS client names without sanitization. Attackers can inject shell metacharacters into client names to execute arbitrary commands as the uMemWatch process user through unquoted redirection targets in system calls.
