Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-45312 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mtproto_proxy (Hex): affected all versions up to 0.7.2; no fix listed\n- mtproto_proxy (Hex): affected all versions up to 0.7.2; no fix listed\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-2023-45312/ (Markdown: https://insights.sbomify.com/CVE-2023-45312/index.md)","id":"CVE-2023-45312","markdown":"https://insights.sbomify.com/CVE-2023-45312/index.md","name":"CVE-2023-45312","record":{"aliases":["GHSA-738q-mc72-2q22"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Erlang MTProto proxy","requires_auth":"low_privilege","summary":"A low-privileged remote attacker can bypass authentication in the default Erlang MTProto proxy installation to achieve remote command execution.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mt_proto_proxy","vendor":"mtproto"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","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-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"In the mtproto_proxy (aka MTProto proxy) component through 0.7.2 for Erlang, a low-privileged remote attacker can access an improperly secured default installation without authenticating and achieve remote command execution ability.","ecosystems":["Hex"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"MTProto proxy remote code execution vulnerability","id":"CVE-2023-45312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":2,"n_references":1,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it is Unused","id":"CVE-2023-45313"},"packages":[{"ecosystem":"Hex","fixed":[],"introduced":["0"],"last_affected":["0.7.2"],"package":"mtproto_proxy","purl":null,"source":"GHSA-738q-mc72-2q22"},{"ecosystem":"Hex","fixed":[],"introduced":["0"],"last_affected":["0.7.2"],"package":"mtproto_proxy","purl":"pkg:hex/mtproto_proxy","source":"GHSA-738q-mc72-2q22"}],"prev":{"headline":"Code injection in fsevents","id":"CVE-2023-45311"},"products":["n/a"],"published":"2023-10-10","related":[],"sources":[{"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-18","vendors":["n/a"]},"summary":"A low-privileged remote attacker can bypass authentication in the default Erlang MTProto proxy installation to achieve remote command execution.","url":"https://insights.sbomify.com/CVE-2023-45312/"}
