As the session cookies are small, an attacker can hijack any existing sessions by bruteforcing the 4 hex-character session cookie on the Windows version (the Linux version appears to have 8 characters). An attacker can obtain the static part of the cookie (cookie name) by first making a request to any page on the application (e.g., /goforms/menu) and saving the name of the cookie sent with the response. The attacker can then use the name of the cookie and try to request that same page, setting a random value for the cookie. If any user has an active session, the page should return with the authorized content, when a valid cookie value is hit.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2021-12-13 04:15:00","updated_at":"2023-08-08 14:22:00"},"problem_types":["CWE-330"],"metrics":[],"references":[{"url":"http://packetstormsecurity.com/files/165191/Reprise-License-Manager-14.2-Session-Hijacking.html","name":"http://packetstormsecurity.com/files/165191/Reprise-License-Manager-14.2-Session-Hijacking.html","refsource":"MISC","tags":[],"title":"Reprise License Manager 14.2 Session Hijacking ≈ Packet Storm","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.reprisesoftware.com/RELEASE_NOTES","name":"https://www.reprisesoftware.com/RELEASE_NOTES","refsource":"CONFIRM","tags":[],"title":"","mime":"text/plain","httpstatus":"200","archivestatus":"200"},{"url":"https://reprisesoftware.com/admin/rlm-admin-download.php?&euagree=yes","name":"https://reprisesoftware.com/admin/rlm-admin-download.php?&euagree=yes","refsource":"MISC","tags":[],"title":"License Administration Bundle Downloads: Reprise License Manager - RLM","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2021-44151","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-44151","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2021","cve_id":"44151","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"reprisesoftware","cpe5":"reprise_license_manager","cpe6":"14.2","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2021-44151","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"An issue was discovered in Reprise RLM 14.2.
