An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-3576 in the wild and no public exploit code.\n\nAffected product: Red Hat Discovery 2. 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-2025-3576/ (Markdown: https://insights.sbomify.com/CVE-2025-3576/index.md)","id":"CVE-2025-3576","markdown":"https://insights.sbomify.com/CVE-2025-3576/index.md","name":"CVE-2025-3576","record":{"aliases":["ALSA-2025:8411","ALSA-2025:9418","ALSA-2025:9430","AZL-60928","CLSA-2025-1751892444","CLSA-2025-1751895517","CLSA-2025-1755113592","CLSA-2025-1755603427","DEBIAN-CVE-2025-3576","DLA-4195-1","ECHO-64ee-f30c-7bc0","GHSA-rfh5-gx7w-h7v7","OESA-2025-2124","OESA-2025-2125","OESA-2025-2126","RHSA-2025:13664","RHSA-2025:13777","RHSA-2025:15000","RHSA-2025:15001","RHSA-2025:15002","RHSA-2025:15003","RHSA-2025:15004","RHSA-2025:8411","RHSA-2025:9418","RHSA-2025:9430","RLSA-2025:8411","RLSA-2025:9418","RLSA-2025:9430","SUSE-SU-2025:03227-1","SUSE-SU-2025:03270-1","SUSE-SU-2025:20719-1","SUSE-SU-2025:3698-1","SUSE-SU-2025:3699-1","SUSE-SU-2025:3729-1","UBUNTU-CVE-2025-3576","USN-7542-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Red Hat Enterprise Linux","requires_auth":"none","summary":"Attackers can spoof GSSAPI messages via MD5 collisions if RC4-HMAC-MD5 is preferred, enabling unauthorized tampering in Red Hat Enterprise Linux environments.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-328","name":"Use of Weak Hash"}],"description":"A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design.
