Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer.

NVD Source

Risk Analysis

OpenVPN versions 2.6.0 through 2.6.6 contain a use-after-free vulnerability that can be triggered by sending specific network buffers. This critical flaw could lead to memory leaks or remote code execution by a remote peer.

No public exploit is known for this issue, and it is not in the CISA KEV. It is remotely exploitable with low complexity.

Recommended Action

Update OpenVPN to a version beyond 2.6.6 to ensure the memory management issue is resolved.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-46850 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-416): Use-after-free vulnerabilities involve accessing memory after it has been freed, often enabling arbitrary code execution.
