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-2023-46724 in the wild and no public exploit code.\n\nAffected product: Squid-Cache Squid. 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-2023-46724/ (Markdown: https://insights.sbomify.com/CVE-2023-46724/index.md)","id":"CVE-2023-46724","markdown":"https://insights.sbomify.com/CVE-2023-46724/index.md","name":"CVE-2023-46724","record":{"aliases":["ALPINE-CVE-2023-46724","AZL-31838","CLSA-2023-1700592773","CLSA-2023-1700592975","CLSA-2023-1701285122","CLSA-2023-1701286147","CLSA-2024-1735126310","DEBIAN-CVE-2023-46724","GHSA-73m6-jm96-c6r3","ROOT-OS-ALPINE-318-CVE-2023-46724","UBUNTU-CVE-2023-46724"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Web caching proxy","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Squid proxy via crafted SSL certificates during TLS handshakes when SSL-Bump or HTTPS is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"squid","vendor":"squid-cache"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-786","name":"Access of Memory Location Before Start of Buffer"},{"id":"CWE-823","name":"Use of Out-of-range Pointer Offset"},{"id":"CWE-129","name":"Improper Validation of Array Index"},{"id":"CWE-1285","name":"Improper Validation of Specified Index, Position, or Offset in Input"},{"id":"CWE-295","name":"Improper Certificate Validation"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Squid is a caching proxy for the Web. Due to an Improper Validation of Specified Index bug, Squid versions 3.3.0.1 through 5.9 and 6.0 prior to 6.4 compiled using `--with-openssl` are vulnerable to a Denial of Service attack against SSL Certificate validation. This problem allows a remote server to perform Denial of Service against Squid Proxy by initiating a TLS Handshake with a specially crafted SSL Certificate in a server certificate chain. This attack is limited to HTTPS and SSL-Bump. This bug is fixed in Squid version 6.4. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. Those who you use a prepackaged version of Squid should refer to the package vendor for availability information on updated packages.","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":"SQUID-2023:4 Denial of Service in SSL Certificate validation","id":"CVE-2023-46724","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"squid-cache:squid","products":["squid-cache:squid"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"FoodCoopShop Server-Side Request Forgery vulnerability","id":"CVE-2023-46725"},"packages":[],"prev":{"headline":"lte-pic32-writer's sendto.txt may disclose URL and the API key","id":"CVE-2023-46723"},"products":["squid"],"published":"2023-11-01","related":[{"cvss_score":10,"headline":"Squid vulnerable to information disclosure via authentication credential leakage in error handling","id":"CVE-2025-62168","kev_date_added":null,"published":"2025-10-17"},{"cvss_score":9.3,"headline":"Squid's URN Handling can lead to Buffer Overflow","id":"CVE-2025-54574","kev_date_added":null,"published":"2025-08-01"},{"cvss_score":9.2,"headline":"Squid vulnerable to Denial of Service in ICP Request handling","id":"CVE-2026-33526","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":8.7,"headline":"Squid has Denial of Service in ICP Response handling","id":"CVE-2026-32748","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":8.6,"headline":"SQUID-2023:10 Denial of Service in HTTP Request parsing","id":"CVE-2023-50269","kev_date_added":null,"published":"2023-12-14"},{"cvss_score":8.6,"headline":"Denial of Service in HTTP Message Processing in Squid","id":"CVE-2023-49285","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.6,"headline":"Denial of Service in Helper Process management","id":"CVE-2023-49286","kev_date_added":null,"published":"2023-12-04"}],"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":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["squid-cache"]},"summary":"Remote attackers can cause a denial of service in Squid proxy via crafted SSL certificates during TLS handshakes when SSL-Bump or HTTPS is enabled.","url":"https://insights.sbomify.com/CVE-2023-46724/"}
