Name of the Vulnerable Software and Affected Versions
NGINX versions prior to 1.13.6
Description
The issue is related to the autoindex module's incorrect handling of years exceeding four digits, which can cause an integer overflow. This can be triggered by a file with a modification date in the distant past or future. The exploitation of this issue may allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
Recommendations
For NGINX versions prior to 1.13.6, update to version 1.13.6 or later to resolve the issue. As a temporary workaround, consider disabling the autoindex module until a patch is available. Restrict access to the autoindex module to minimize the risk of exploitation.
