Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-23642 exists.\n\nAffected product: sourcegraph. 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-2022-23642/ (Markdown: https://insights.sbomify.com/CVE-2022-23642/index.md)","id":"CVE-2022-23642","markdown":"https://insights.sbomify.com/CVE-2022-23642/index.md","name":"CVE-2022-23642","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Sourcegraph code search","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code by manipulating git configuration via the gitserver service in Sourcegraph deployments.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sourcegraph","vendor":"sourcegraph"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Sourcegraph is a code search and navigation engine. Sourcegraph prior to version 3.37 is vulnerable to remote code execution in the `gitserver` service. The service acts as a git exec proxy, and fails to properly restrict calling `git config`. This allows an attacker to set the git `core.sshCommand` option, which sets git to use the specified command instead of ssh when they need to connect to a remote system. Exploitation of this vulnerability depends on how Sourcegraph is deployed. An attacker able to make HTTP requests to internal services like gitserver is able to exploit it. This issue is patched in Sourcegraph version 3.37. As a workaround, ensure that requests to gitserver are properly protected.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2022-02-18","github_poc":1,"max_poc_stars":7,"metasploit":1,"nuclei":0,"refs":[{"date":"2022-06-10T06:12:15Z","kind":"github_poc","ref":"https://github.com/Altelus1/CVE-2022-23642","stars":7,"title":"PoC for Sourcegraph Gitserver \u003c 3.37.0 RCE (CVE-2022-23642)"},{"date":"2022-02-18","kind":"metasploit","ref":"exploit/linux/http/sourcegraph_gitserver_sshcmd","stars":null,"title":"Sourcegraph gitserver sshCommand RCE"},{"date":"2022-06-14","kind":"exploitdb","ref":"50964","stars":null,"title":"Sourcegraph Gitserver 3.36.3 - Remote Code Execution (RCE)"}],"tier":"weaponised"},"has_fix":null,"headline":"Code Injection in Sourcegraph","id":"CVE-2022-23642","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"Side-channel attack in Sourcegraph Code Monitors","id":"CVE-2022-23643"},"packages":[],"prev":{"headline":"Denial of Service in Discourse","id":"CVE-2022-23641"},"products":["sourcegraph"],"published":"2022-02-18","related":[{"cvss_score":9,"headline":"Incorrect default permissions found in Sourcegraph","id":"CVE-2022-41943","kev_date_added":null,"published":"2022-11-22"},{"cvss_score":7.9,"headline":"Sourcegraph vulnerable to Comand Injection via gitserver","id":"CVE-2022-41942","kev_date_added":null,"published":"2022-11-22"},{"cvss_score":6.6,"headline":"Remote Code Execution in sourcegraph","id":"CVE-2022-29171","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":6.5,"headline":"Side-channel attack in Sourcegraph Code Monitors","id":"CVE-2022-23643","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":6.5,"headline":"Side-channel attack in Sourcegraph","id":"CVE-2021-43823","kev_date_added":null,"published":"2021-12-13"},{"cvss_score":6.4,"headline":"Indirect Object Access in Sourcegraph Code Monitoring","id":"CVE-2022-31154","kev_date_added":null,"published":"2022-08-01"}],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["sourcegraph"]},"summary":"Attackers can execute arbitrary code by manipulating git configuration via the gitserver service in Sourcegraph deployments.","url":"https://insights.sbomify.com/CVE-2022-23642/"}
