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-2006-0743 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- log4net (NuGet): affected all versions; fixed in 1.2.10\n- log4net (NuGet): affected all versions; fixed in 1.2.10\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-2006-0743/ (Markdown: https://insights.sbomify.com/CVE-2006-0743/index.md)","id":"CVE-2006-0743","markdown":"https://insights.sbomify.com/CVE-2006-0743/index.md","name":"CVE-2006-0743","record":{"aliases":["GHSA-f9fr-w54q-772h","openSUSE-SU-2024:10072-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"log4net logging library","requires_auth":"none","summary":"Remote attackers can cause denial of service via memory corruption in the LocalSyslogAppender component of the log4net library.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"log4net","vendor":"apache"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"Format string vulnerability in LocalSyslogAppender in Apache log4net 1.2.9 might allow remote attackers to cause a denial of service (memory corruption and termination) via unknown vectors.","ecosystems":["NuGet","openSUSE:Tumbleweed"],"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":"Apache log4net format string vulnerability causes DoS","id":"CVE-2006-0743","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"memory_corruption","year":"2006"},"n_packages":3,"n_references":8,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2006-0744"},"packages":[{"ecosystem":"NuGet","fixed":["1.2.10"],"introduced":["0"],"last_affected":[],"package":"log4net","purl":null,"source":"GHSA-f9fr-w54q-772h"},{"ecosystem":"NuGet","fixed":["1.2.10"],"introduced":["0"],"last_affected":[],"package":"log4net","purl":"pkg:nuget/log4net","source":"GHSA-f9fr-w54q-772h"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.2.10-75.6"],"introduced":["0"],"last_affected":[],"package":"log4net","purl":"pkg:rpm/opensuse/log4net\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:10072-1"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2006-0742"},"products":["n/a"],"published":"2006-03-09","related":[{"cvss_score":9.8,"headline":"XML External Entity attack in log4net","id":"CVE-2018-1285","kev_date_added":null,"published":"2020-05-11"},{"cvss_score":6.3,"headline":"Apache Log4net: Silent log event loss in XmlLayout and XmlLayoutSchemaLog4J due to unescaped XML 1.0 forbidden characters","id":"CVE-2026-40021","kev_date_added":null,"published":"2026-04-10"},{"cvss_score":5.3,"headline":"Apache log4net: NUL character truncates EventLogAppender records","id":"CVE-2026-105239","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":5.3,"headline":"Apache log4net: NUL character truncates OutputDebugStringAppender records","id":"CVE-2026-105240","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":5.3,"headline":"Apache log4net: Unencodable content discards a whole SmtpPickupDirAppender batch","id":"CVE-2026-105241","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":5.3,"headline":"Apache log4net: Request validation failure drops the event in the aspnet-request converter","id":"CVE-2026-105242","kev_date_added":null,"published":"2026-10-06"},{"cvss_score":5.3,"headline":"Apache log4net: Oversize EventLogAppender record silently discarded","id":"CVE-2026-105243","kev_date_added":null,"published":"2026-10-06"}],"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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service via memory corruption in the LocalSyslogAppender component of the log4net library.","url":"https://insights.sbomify.com/CVE-2006-0743/"}
