Arbitrary File Write in Ivanti Connect Secure and Ivanti Policy Secure

IdentifiersCVE-2024-38657CWE-73· External Control of File Name or…

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.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated remote attacker with admin privileges to write arbitrary files to the appliance. This can compromise system integrity, alter configuration or operational files, and potentially facilitate follow-on actions such as persistence, service manipulation, or code execution if attacker-controlled files can be placed in sensitive locations and later processed by the system.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict administrative access to trusted management networks and minimize the number of accounts with administrator privileges. Enforce strong authentication for administrative interfaces, monitor for unexpected file creation or modification on affected appliances, and review administrative activity for signs of abuse. These are compensating controls only; vendor updates are the primary mitigation.

Remediation

Patch, then assume compromise.

Upgrade Ivanti Connect Secure to 22.7R2.4 or later and Ivanti Policy Secure to 22.7R1.3 or later. Apply the latest vendor-provided software updates from Ivanti's official download portal and prioritize patching because these product lines are routinely targeted.
