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-2022-39269 in the wild and no public exploit code.\n\nAffected product: pjsip pjproject. 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-2022-39269/ (Markdown: https://insights.sbomify.com/CVE-2022-39269/index.md)","id":"CVE-2022-39269","markdown":"https://insights.sbomify.com/CVE-2022-39269/index.md","name":"CVE-2022-39269","record":{"aliases":["ALPINE-CVE-2022-39269","DEBIAN-CVE-2022-39269","GHSA-wx5m-cj97-4wwg","UBUNTU-CVE-2022-39269"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PJSIP multimedia library","requires_auth":"none","summary":"Attackers can force PJSIP to downgrade secure SRTP media to insecure RTP, exposing communication content to eavesdropping.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"pjsip","vendor":"teluu"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"PJSIP is a free and open source multimedia communication library written in C. When processing certain packets, PJSIP may incorrectly switch from using SRTP media transport to using basic RTP upon SRTP restart, causing the media to be sent insecurely. The vulnerability impacts all PJSIP users that use SRTP. The patch is available as commit d2acb9a in the master branch of the project and will be included in version 2.13. Users are advised to manually patch or to upgrade. There are no known workarounds for this vulnerability.","ecosystems":[],"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":"Media transport downgrade from the secure version (SRTP) to non-secure (RTP) in pjsip","id":"CVE-2022-39269","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"Arbitrary HTML injection in table-of-contents theme component in DiscoTOC","id":"CVE-2022-39270"},"packages":[],"prev":{"headline":"orchest vulnerable to cross-site request forgery that allows control of a user instance","id":"CVE-2022-39268"},"products":["pjproject"],"published":"2022-10-06","related":[{"cvss_score":9.8,"headline":"PJSIP has use-after-free vulnerability in SRTP media transport","id":"CVE-2023-38703","kev_date_added":null,"published":"2023-10-06"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow handling Service-Route headers in a registration response","id":"CVE-2026-57161","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow parsing SDP a=crypto attributes","id":"CVE-2026-57162","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.8,"headline":"PJSIP: Stack overflow parsing a TLS peer certificate's SubjectAltName in GnuTLS backend","id":"CVE-2026-57163","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.4,"headline":"PJSIP: SDP parser out-of-bounds write in remote payload-type map maintenance","id":"CVE-2026-57159","kev_date_added":null,"published":"2026-09-04"},{"cvss_score":8.3,"headline":"PJSIP: Heap overflow in the HTTP client","id":"CVE-2026-57164","kev_date_added":null,"published":"2026-09-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["pjsip"]},"summary":"Attackers can force PJSIP to downgrade secure SRTP media to insecure RTP, exposing communication content to eavesdropping.","url":"https://insights.sbomify.com/CVE-2022-39269/"}
