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-2025-55753 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.30; fixed in 2.4.66\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-2025-55753/ (Markdown: https://insights.sbomify.com/CVE-2025-55753/index.md)","id":"CVE-2025-55753","markdown":"https://insights.sbomify.com/CVE-2025-55753/index.md","name":"CVE-2025-55753","record":{"aliases":["ALPINE-CVE-2025-55753","ALSA-2025:23738","ALSA-2025:23739","AZL-71851","AZL-71858","AZL-71863","AZL-71870","BELL-CVE-2025-55753","BIT-apache-2025-55753","CLSA-2025-1767026442","CLSA-2026-1767629031","DEBIAN-CVE-2025-55753","GHSA-3j5h-f552-7rhh","MINI-cqqf-m5p4-rcx3","OESA-2026-1064","OESA-2026-1530","RHSA-2025:23738","RHSA-2025:23739","RHSA-2026:0029","RHSA-2026:0030","RHSA-2026:0092","RHSA-2026:0093","RHSA-2026:0094","RLSA-2025:23738","RLSA-2025:23739","UBUNTU-CVE-2025-55753"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"Integer overflow in Apache mod_md causes zero-delay certificate renewal retries, leading to excessive resource consumption and potential denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0.
