It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-2746 in the wild and no public exploit code.\n\nAffected product: Fedora dnf5daemon-server. 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-2024-2746/ (Markdown: https://insights.sbomify.com/CVE-2024-2746/index.md)","id":"CVE-2024-2746","markdown":"https://insights.sbomify.com/CVE-2024-2746/index.md","name":"CVE-2024-2746","record":{"aliases":["AZL-40346","GHSA-rpc3-mw2p-39mj"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux package manager","requires_auth":"low_privilege","summary":"Local attackers can exploit incomplete fixes in dnf5 D-Bus daemon to achieve root privileges or cause denial of service via malicious configuration files.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Incomplete fix for CVE-2024-1929\n\nThe problem with CVE-2024-1929 was that the dnf5 D-Bus daemon accepted arbitrary configuration parameters from unprivileged users, which allowed a\nlocal root exploit by tricking the daemon into loading a user controlled \"plugin\". All of this happened before Polkit authentication was even started.\n\nThe dnf5 library code does not check whether non-root users control the directory in question. \n\nOn one hand, this poses a Denial-of-Service attack vector by making the daemonoperate on a blocking file (e.g. named FIFO special file) or a very large file\nthat causes an out-of-memory situation (e.g. /dev/zero). On the other hand, this can be used to let the daemon process privileged files like /etc/shadow.\nThe file in question is parsed as an INI file. Error diagnostics resulting from parsing privileged files could cause information leaks, if these diagnostics\nare accessible to unprivileged users. In the case of libdnf5, no such user accessible diagnostics should exist, though.\n\nAlso, a local attacker can place a valid repository configuration file in this directory. This configuration file allows to specify\na plethora of additional configuration options. This makes various additional code paths in libdnf5 accessible to the attacker.","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":"Incomplete fix for CVE-2024-1929","id":"CVE-2024-2746","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Easergy Studio","id":"CVE-2024-2747"},"packages":[],"prev":{"headline":"Rapid7 InsightVM Sensitive Information Exposure via URL","id":"CVE-2024-2745"},"products":["dnf5daemon-server"],"published":"2024-05-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-12","vendors":["Fedora"]},"summary":"Local attackers can exploit incomplete fixes in dnf5 D-Bus daemon to achieve root privileges or cause denial of service via malicious configuration files.","url":"https://insights.sbomify.com/CVE-2024-2746/"}
