Name of the Vulnerable Software and Affected Versions
ua-parser-js versions 0.7.30 through 0.7.32
ua-parser-js versions 0.8.1 through 1.0.32
Description
A regular expression denial of service (ReDoS) issue has been discovered in ua-parser-js, allowing an attacker to craft a long user-agent string with a specific pattern, causing the script to get stuck processing for a long time and resulting in a denial of service (DoS) condition. This vulnerability bypasses the library's MAX LENGTH input limit prevention.
Recommendations
For ua-parser-js versions 0.7.30 through 0.7.32, update to version 0.7.33 or later.
For ua-parser-js versions 0.8.1 through 1.0.32, update to version 1.0.33 or later.
As a temporary workaround, consider restricting the input to the trim() function to prevent exploitation until a patch is applied.
