The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has mercurial packages installed that are affected by multiple vulnerabilities:
Mercurial version 4.5 and earlier contains a Incorrect Access Control (CWE-285) vulnerability in Protocol server that can result in Unauthorized data access. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in 4.5.1. (CVE-2018-1000132)
The mpatch_apply function in mpatch.c in Mercurial before 4.6.1 incorrectly proceeds in cases where the fragment start is past the end of the original data, aka OVE-20180430-0004. (CVE-2018-13346)
mpatch.c in Mercurial before 4.6.1 mishandles integer addition and subtraction, aka OVE-20180430-0002.
(CVE-2018-13347)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
