Attackers can induce a victim's browser to load /api/session/openid/callback with their own authorization code, causing data the victim enters, such as registered devices, to land in the attacker's account.","cvssScore":4.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","cwes":["CWE-352"],"vendors":[],"products":[],"references":[{"url":"https://github.com/traccar/traccar","tags":[]},{"url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/api/resource/SessionResource.java#L175-L193","tags":[]},{"url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/database/OpenIdProvider.java#L110-L198","tags":[]},{"url":"https://hackmd.io/@haind/traccar-oidc-client-missing-state-login-csrf","tags":[]},{"url":"https://www.vulncheck.com/advisories/traccar-5.7-through-6.16.0-login-csrf-via-openid-connect-callback","tags":[]}],"exploitRefs":[{"url":"https://github.com/traccar/traccar","tags":[]},{"url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/api/resource/SessionResource.java#L175-L193","tags":[]},{"url":"https://github.com/traccar/traccar/blob/cfab560c79ee9c9eaa41c79c6df351e820d6284b/src/main/java/org/traccar/database/OpenIdProvider.java#L110-L198","tags":[]}],"hasPoc":true,"ai":null}
