"The remote host is affected by the vulnerability described in GLSA-202405-16 (Apache Commons BCEL: Remote Code
Execution)

  - The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious
    XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler
    and execute arbitrary Java bytecode. Users are recommended to update to version 2.7.3 or later. Note: Java
    runtimes (such as OpenJDK) include repackaged copies of Xalan. (CVE-2022-34169)

  - Apache Commons BCEL has a number of APIs that would normally only allow changing specific class
    characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce
    arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those
    APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to
    Apache Commons BCEL 6.6.0. (CVE-2022-42920)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
