CVE-2022-45378
CWE-306Published: November 14, 2022· Updated: Jun 17, 2026
Official Description
In the default configuration of Apache SOAP, an RPCRouterServlet is available without authentication. This gives an attacker the possibility to invoke methods on the classpath that meet certain criteria. Depending on what classes are available on the classpath this might even lead to arbitrary remote code execution. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
Risk Analysis
Apache SOAP contains an unauthenticated RPCRouterServlet that allows remote attackers to invoke methods on the classpath. This can lead to arbitrary remote code execution depending on available classes. The critical CVSS score reflects the potential for full system compromise.
There is no known public exploit for this vulnerability, and it is not in the CISA KEV catalog. It is remotely exploitable with low attack complexity.
This vulnerability affects products that are no longer supported by the maintainer; users should migrate to a supported alternative.
Technical Analysis
CVE-2022-45378 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.
