CVS Undocumented Flag Information Disclosure Vulnerability (history.c)
------------------------------------------------------------------------
SUMMARY
CVS (Concurrent Versions System) is "an open-source network-transparent
version control system".
Remote exploitation of an information disclosure vulnerability in
Concurrent Versions Systems (CVS) allows attackers to glean information.
DETAILS
Vulnerable Systems:
* CVS version 1.11 and prior
Immune Systems:
* CV version 1.11.17, version 1.12.9, or newer
The vulnerability exists within an undocumented switch to the 'history'
command implemented in src/history.c. The -X command specifies the name of
the history file allowing an attacker to determine whether arbitrary
system files and directories exist and whether or not the CVS process has
access to them.
Analysis:
Successful exploitation allows remote attackers with credentials to the
affected CVS server to determine whether or not arbitrary system files and
directories exist and are accessible under the permissions of the user
that the CVS daemon runs under.
