It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-21724 exists.\n\nAffected packages and fixed versions:\n- org.postgresql:postgresql (Maven): affected from 42.3.0; fixed in 42.3.2\n- org.postgresql:postgresql (Maven): affected from 42.3.0; fixed in 42.3.2\n- org.postgresql:postgresql (Maven): affected from 9.4.1208; fixed in 42.2.25\n- org.postgresql:postgresql (Maven): affected from 9.4.1208; fixed in 42.2.25\n- postgresql-jdbc-driver (Bitnami): affected all versions; fixed in 42.2.25, 42.3.2\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-2022-21724/ (Markdown: https://insights.sbomify.com/CVE-2022-21724/index.md)","id":"CVE-2022-21724","markdown":"https://insights.sbomify.com/CVE-2022-21724/index.md","name":"CVE-2022-21724","record":{"aliases":["BIT-postgresql-jdbc-driver-2022-21724","CLEANSTART-2026-ZQ49670","CLSA-2026-1775033648","DEBIAN-CVE-2022-21724","DLA-3018-1","GHSA-v7wg-cpwc-24m4","MINI-h5f2-x5fv-p23j","MINI-jfcf-fqxp-3hfc","MINI-xwvg-3933-m7vh","OESA-2022-1535","UBUNTU-CVE-2022-21724"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"PostgreSQL JDBC Driver","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code by providing malicious class names in connection properties, requiring an upgrade to the PostgreSQL JDBC Driver.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"postgresql_jdbc_driver","vendor":"postgresql"},{"product":"quarkus","vendor":"quarkus"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-665","name":"Improper Initialization"}],"description":"pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in the jdbc driver for postgresql database while doing security research. The system using the postgresql library will be attacked when attacker control the jdbc url or properties. pgjdbc instantiates plugin instances based on class names provided via `authenticationPluginClassName`, `sslhostnameverifier`, `socketFactory`, `sslfactory`, `sslpasswordcallback` connection properties. However, the driver did not verify if the class implements the expected interface before instantiating the class. This can lead to code execution loaded via arbitrary classes. Users using plugins are advised to upgrade. There are no known workarounds for this issue.","ecosystems":["Bitnami","Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Unchecked Class Instantiation when providing Plugin Classes","id":"CVE-2022-21724","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora"],"type":"code_injection","year":"2022"},"n_packages":5,"n_references":6,"next":{"headline":"Division by zero in Tensorflow","id":"CVE-2022-21725"},"packages":[{"ecosystem":"Bitnami","fixed":["42.2.25","42.3.2"],"introduced":["0","42.3.0"],"last_affected":[],"package":"postgresql-jdbc-driver","purl":"pkg:bitnami/postgresql-jdbc-driver","source":"BIT-postgresql-jdbc-driver-2022-21724"},{"ecosystem":"Maven","fixed":["42.3.2"],"introduced":["42.3.0"],"last_affected":[],"package":"org.postgresql:postgresql","purl":null,"source":"GHSA-v7wg-cpwc-24m4"},{"ecosystem":"Maven","fixed":["42.3.2"],"introduced":["42.3.0"],"last_affected":[],"package":"org.postgresql:postgresql","purl":"pkg:maven/org.postgresql/postgresql","source":"GHSA-v7wg-cpwc-24m4"},{"ecosystem":"Maven","fixed":["42.2.25"],"introduced":["9.4.1208"],"last_affected":[],"package":"org.postgresql:postgresql","purl":null,"source":"GHSA-v7wg-cpwc-24m4"},{"ecosystem":"Maven","fixed":["42.2.25"],"introduced":["9.4.1208"],"last_affected":[],"package":"org.postgresql:postgresql","purl":"pkg:maven/org.postgresql/postgresql","source":"GHSA-v7wg-cpwc-24m4"}],"prev":{"headline":"Out-of-bounds read in multipart parsing in PJSIP","id":"CVE-2022-21723"},"products":["n/a"],"published":"2022-02-02","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-05","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by providing malicious class names in connection properties, requiring an upgrade to the PostgreSQL JDBC Driver.","url":"https://insights.sbomify.com/CVE-2022-21724/"}
