NewStart CGSL CORE 5.04 / MAIN 5.04 : git Vulnerability (NS-SA-2019-0027)
Medium Nessus Plugin ID 127189
SynopsisThe remote machine is affected by a vulnerability.
DescriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has git packages installed that are affected by a vulnerability:
- In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs git clone
--recurse-submodules because submodule names are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with ../ in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL git packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
