Exploitation Status

No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

SourceMonitor Plugin 0.2 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control XML input files for the 'Publish SourceMonitor results' post-build step to have agent processes parse a crafted file that uses external entities for extraction of secrets from the Jenkins agent or server-side request forgery.

Because Jenkins agent processes usually execute build tools whose input (source code, build scripts, etc.) is controlled externally, this vulnerability only has a real impact in very narrow circumstances: when attackers can control XML files, but are unable to change build steps, Jenkinsfiles, test code that gets executed on the agents, or similar.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.thalesgroup.hudson.plugins:sourcemonitor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of com.thalesgroup.hudson.plugins:sourcemonitor for CVE-2022-45396. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
