Official Description
drachtio-server 0.8.18 has a request-handler.cpp event_cb use-after-free for any request.
Risk Analysis
The drachtio-server version 0.8.18 is vulnerable to a use-after-free condition in its request handling logic. This critical 9.8 CVSS flaw could allow an attacker to trigger memory corruption, potentially leading to remote code execution.
No public exploit is known, and it is not in the CISA KEV. The vulnerability is remotely exploitable with low attack complexity.
Upgrade drachtio-server to a version that addresses this memory management issue. Monitor server logs for unusual crashes or behavior.
Technical Analysis
CVE-2022-45474 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.
