An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-22521 in the wild and no public exploit code.\n\nAffected product: Atlassian Crowd Data Center. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-22521/ (Markdown: https://insights.sbomify.com/CVE-2023-22521/index.md)","id":"CVE-2023-22521","markdown":"https://insights.sbomify.com/CVE-2023-22521/index.md","name":"CVE-2023-22521","record":{"aliases":["GHSA-m6fg-m377-682m"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Crowd","requires_auth":"high_privilege","summary":"Authenticated attackers can execute arbitrary code on Atlassian Crowd servers, compromising confidentiality, integrity, and availability.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"crowd","vendor":"atlassian"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"This High severity RCE (Remote Code Execution) vulnerability was introduced in version 3.4.6 of Crowd Data Center and Server.\r\n\r\nThis RCE (Remote Code Execution) vulnerability, with a CVSS Score of 8.0, allows an authenticated attacker to execute arbitrary code which has high impact to confidentiality, high impact to integrity, high impact to availability, and requires no user interaction.\r\n\r\nAtlassian recommends that Crowd Data Center and Server customers upgrade to latest version, if you are unable to do so, upgrade your instance to one of the specified supported fixed versions:\r\n Crowd Data Center and Server 3.4: Upgrade to a release greater than or equal to 5.1.6\r\n Crowd Data Center and Server 5.2: Upgrade to a release greater than or equal to 5.2.1\r\n\r\nSee the release notes ([https://confluence.atlassian.com/crowd/crowd-release-notes-199094.html]).
