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-2020-17525 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- subversion (Bitnami): affected from 1.9.0; fixed in 1.10.7, 1.14.1\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-2020-17525/ (Markdown: https://insights.sbomify.com/CVE-2020-17525/index.md)","id":"CVE-2020-17525","markdown":"https://insights.sbomify.com/CVE-2020-17525/index.md","name":"CVE-2020-17525","record":{"aliases":["ALPINE-CVE-2020-17525","ALSA-2021:0507","AZL-6899","BIT-subversion-2020-17525","CLSA-2022-1660064148","DEBIAN-CVE-2020-17525","DLA-2646-1","DSA-4851-1","GHSA-w6m8-jhpf-wj94","MGASA-2021-0091","RHSA-2021:0507","RHSA-2021:0508","RHSA-2021:0509","RLSA-2021:0507","SUSE-SU-2021:0424-1","SUSE-SU-2021:0425-1","UBUNTU-CVE-2020-17525","USN-5322-1","openSUSE-SU-2021:0280-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Subversion mod_authz_svn","requires_auth":"none","summary":"Remote attackers can crash the Subversion server by requesting a non-existent repository URL when specific authz options are enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"subversion","vendor":"apache"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL.
