CVE-2018-7158
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Node.js versions 4.x
Description
The issue concerns a potential regular expression denial of service (ReDoS) vector in the
'path' module. This module is used for various path parsing functions, including path.dirname(), path.extname(), and path.parse(). An attacker can craft a string that, when passed through one of these functions, could take a significant amount of time to evaluate, potentially leading to a full denial of service.Recommendations
For Node.js versions 4.x, consider upgrading to Node.js 6.x or later, as the code in question was replaced in these versions, resolving the issue. As a temporary workaround, consider restricting the use of the
'path' module or the specific functions path.dirname(), path.extname(), and path.parse() to minimize the risk of exploitation.Exploit
