Open advisories
3 actionable advisories, newest first. Withdrawn advisories and news are excluded. Coverage is partial.
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.
Recommended action: Upgrade to 0.11.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
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 >= v0.7.3 Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes. Details Each vulnerable regular expression reported here contains 3 overlapping capture groups. Backtracking has approximately cubic time complexity with respect to the length of the user-agent string. Regex 1: is vulnerable in portion ([^;]+) and can be attacked with e.g. Regex 2: is vulnerable in portion \d+[^\);]+[^\);] and can be attacked with Regex 3: is vulnerable in portion ([^;]) and can be attacked with Regex 4: is vulnerable in portions (?:CUS:([^;])|([^;]+)) and ([^;]) and can be attacked with Reported by Ben Caller @bcaller

An issue was discovered in regex.yaml (aka regexes.yaml) in UA-Parser UAP-Core before 0.6.0. A Regular Expression Denial of Service (ReDoS) issue allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to a value containing a long digit string. (The UAP-Core project contains the vulnerability, propagating to all implementations.)
