Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-10754 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apereo.cas:cas-server-core-services-api (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-core-services-api (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-core-services-authentication (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-core-services-authentication (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-oauth-core-api (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-oauth-core-api (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-oidc (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-oidc (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-shell (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-shell (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-simple-mfa (Maven): affected all versions; fixed in 6.1.0-RC5\n- org.apereo.cas:cas-server-support-simple-mfa (Maven): affected all versions; fixed in 6.1.0-RC5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-10754/ (Markdown: https://insights.sbomify.com/CVE-2019-10754/index.md)","id":"CVE-2019-10754","markdown":"https://insights.sbomify.com/CVE-2019-10754/index.md","name":"CVE-2019-10754","record":{"aliases":["GHSA-g24w-373r-5pxg"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Apereo CAS","requires_auth":"low_privilege","summary":"Predictable token generation in Apereo CAS allows attackers to bypass authentication or take over accounts due to weak random number generation.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"central_authentication_service","vendor":"apereo"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"Multiple classes used within Apereo CAS before release 6.1.0-RC5 makes use of apache commons-lang3 RandomStringUtils for token and ID generation which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use of Insufficiently Random Values in Apereo CAS","id":"CVE-2019-10754","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"weak_cryptography","year":"2019"},"n_packages":12,"n_references":5,"next":{"headline":"Use of Cryptographically Weak Pseudo-Random Number Generator in org.pac4j:pac4j-saml","id":"CVE-2019-10755"},"packages":[{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-core-services-api","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-core-services-api","purl":"pkg:maven/org.apereo.cas/cas-server-core-services-api","source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-core-services-authentication","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-core-services-authentication","purl":"pkg:maven/org.apereo.cas/cas-server-core-services-authentication","source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-oauth-core-api","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-oauth-core-api","purl":"pkg:maven/org.apereo.cas/cas-server-support-oauth-core-api","source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-oidc","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-oidc","purl":"pkg:maven/org.apereo.cas/cas-server-support-oidc","source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-shell","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-shell","purl":"pkg:maven/org.apereo.cas/cas-server-support-shell","source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-simple-mfa","purl":null,"source":"GHSA-g24w-373r-5pxg"},{"ecosystem":"Maven","fixed":["6.1.0-RC5"],"introduced":["0"],"last_affected":[],"package":"org.apereo.cas:cas-server-support-simple-mfa","purl":"pkg:maven/org.apereo.cas/cas-server-support-simple-mfa","source":"GHSA-g24w-373r-5pxg"}],"prev":{"headline":"Incorrect Resource Transfer Between Spheres in eclipse-wtp","id":"CVE-2019-10753"},"products":["Apereo CAS"],"published":"2019-09-23","related":[{"cvss_score":9.8,"headline":"MFA bypass in Apereo CAS","id":"CVE-2023-4612","kev_date_added":null,"published":"2023-11-09"},{"cvss_score":9.1,"headline":"CAS \u003c= 1.0.0 -
