Arbitrary File Write in Ivanti Connect Secure and Ivanti Policy Secure
CVE-2024-38657 is an external control of file name vulnerability affecting Ivanti Connect Secure before 22.7R2.4 and Ivanti Policy Secure before 22.7R1.3. The issue allows a remote authenticated attacker with administrator privileges to write arbitrary files on the target appliance. Based on the provided description, the flaw stems from insufficient restriction of attacker-controlled file names during file write operations, enabling an administrative user to influence the destination or name of written files. Successful exploitation can compromise the integrity of the underlying system and may enable further post-exploitation activity depending on what files are overwritten or created.
