Versions starting with 2.2 and prior to 2.3.19, 2.4.7, and 2.5.0-beta.2 are vulnerable to regular expression denial of service (ReDoS) attacks. By using specific a RegularExpression, an attacker can cause denial of service for the bbb-html5 service. The useragent library performs checking of device by parsing the input of User-Agent header and lets it go through lookupUserAgent() (alias of useragent.lookup() ). This function handles input by regexing and attackers can abuse that by providing some ReDos payload using `SmartWatch`. The maintainers removed `htmlclient/useragent` from versions 2.3.19, 2.4.7, and 2.5.0-beta.2. As a workaround, disable NginX forwarding the requests to the handler according to the directions in the GitHub Security Advisory." } ] + }, + "impact": { + "cvss": { + "attackComplexity": "LOW", + "attackVector": "NETWORK", + "availabilityImpact": "HIGH", + "baseScore": 7.5, + "baseSeverity": "HIGH", + "confidentialityImpact": "NONE", + "integrityImpact": "NONE", + "privilegesRequired": "NONE", + "scope": "UNCHANGED", + "userInteraction": "NONE", + "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", + "version": "3.1" + } + }, + "problemtype": { + "problemtype_data": [ + { + "description": [ + { + "lang": "eng", + "value": "CWE-20: Improper Input Validation" + } + ] + } + ] + }, + "references": { + "reference_data": [ + { + "name": "https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-rwrv-p665-4vwp", + "refsource": "CONFIRM", + "url": "https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-rwrv-p665-4vwp" + }, + { + "name": "https://github.com/bigbluebutton/bigbluebutton/pull/14886", + "refsource": "MISC", + "url": "https://github.com/bigbluebutton/bigbluebutton/pull/14886" + }, + { + "name": "https://github.com/bigbluebutton/bigbluebutton/pull/14896", + "refsource": "MISC", + "url": "https://github.com/bigbluebutton/bigbluebutton/pull/14896" + } + ] + }, + "source": { + "advisory": "GHSA-rwrv-p665-4vwp", + "discovery": "UNKNOWN" } } \ No newline at end of file
