Description


A vulnerability has been reported in Apache CXF, which can be exploited by malicious people to disclose system information or potentially sensitive information and cause a DoS (Denial of Service).

The vulnerability is caused due to CXF not properly restricting the processing of XML Document Type Declarations (DTD). This can be exploited to e.g. determine the existence or include contents of local and potentially external files by including them as a DTD reference or cause a DoS due to CPU or memory consumption by providing e.g. a heavily nested DTD.

The vulnerability has been reported in versions prior to 2.0.13, 2.1.10, and 2.2.9.


Solution:
Update to version 2.0.13, 2.1.10, or 2.2.9.

Provided and/or discovered by:
Reported by the vendor.
