Description


A vulnerability has been reported in Apache Axis2/Java, 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 Axis2 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 is reported in version 1.4.1 and 1.5.1. Prior versions may also be affected.


Solution:
Apply patch and update to version 1.5.2 or 1.6 as soon as available. See vendor's advisory for additional details.
