GHSA-P4PJ-MG4R-X6V4

Vulnerability from github – Published: 2021-02-02 15:46 – Updated: 2024-02-08 22:17

Summary

Denial of Service in uap-core

Details

Impact

Some regexes are vulnerable to regular expression denial of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings.

Patches

Please update uap-core to >= v0.11.0

Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes.

Severity ?

7.5 (High)

CVE-2021-21317 (GCVE-0-2021-21317)

Vulnerability from cvelistv5 – Published: 2021-02-16 17:45 – Updated: 2024-08-03 18:09

Title

Denial of Service in uap-core

Summary

uap-core in an open-source npm package which contains the core of BrowserScope's original user agent string parser. In uap-core before version 0.11.0, some regexes are vulnerable to regular expression denial of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings. This is fixed in version 0.11.0. Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes.

Severity ?
