Remote Code Execution in Ivanti Connect Secure Stack-Based Buffer Overflow

IdentifiersCVE-2025-22467CWE-121· Stack-based Buffer Overflow

CVE-2025-22467 is a critical stack-based buffer overflow vulnerability in Ivanti Connect Secure affecting versions prior to 22.7R2.6, including 22.7R2.5 and earlier. The flaw allows a remote authenticated attacker to trigger memory corruption via a vulnerable code path in the appliance, resulting in arbitrary code execution on the affected device. The provided content identifies the issue specifically as a stack-based buffer overflow and states that exploitation can lead to remote code execution on vulnerable Ivanti Connect Secure systems.

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 arbitrary code execution on the vulnerable Ivanti Connect Secure appliance. Because the flaw affects a security gateway/VPN appliance, compromise could enable full takeover of the device, loss of integrity and confidentiality of data handled by the appliance, and use of the system as a foothold for further intrusion activity. The content describes the issue as critical and notes that Ivanti products are continuously targeted, increasing operational risk for exposed vulnerable deployments.

Mitigation

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

If immediate patching is not possible, reduce exposure of Ivanti Connect Secure management and access interfaces to only trusted networks and users, minimize the number of accounts that can authenticate to the appliance, and closely monitor the device for signs of compromise or anomalous authenticated activity. However, the available content emphasizes prompt patching as the primary mitigation and does not provide a vendor-specific workaround.

Remediation

Patch, then assume compromise.

Upgrade Ivanti Connect Secure to version 22.7R2.6 or later. The provided content states that versions 22.7R2.5 and earlier are vulnerable and that Ivanti fixed the issue in 22.7R2.6. Ivanti advised customers to update vulnerable devices immediately using the vendor-provided software available through the Ivanti download portal.
