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.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","level":"high","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-09","score":0.02612,"percentile":0.8553,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-330","CWE-384"],"published":"2021-12-13T00:00:00Z","modified":"2026-06-17T04:11:57Z","products":[{"vendor":"reprisesoftware","product":"reprise_license_manager"}],"references":[{"url":"https://reprisesoftware.com/admin/rlm-admin-download.php?\u0026euagree=yes","tags":["x_transferred","Product","Vendor Advisory"]},{"url":"http://packetstormsecurity.com/files/165191/Reprise-License-Manager-14.2-Session-Hijacking.html","tags":["x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://www.reprisesoftware.com/RELEASE_NOTES","tags":["x_transferred","Broken Link"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-44151"},{"url":"https://github.com/advisories/GHSA-2x2v-ccf2-cqcf"}],"sources":{"cve":[{"id":"CVE-2021-44151","description":"An issue was discovered in Reprise RLM 14.2.
