Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-43661 in the wild and no public exploit code.\n\nAffected product: Iocharger firmware for AC models. 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-2024-43661/ (Markdown: https://insights.sbomify.com/CVE-2024-43661/index.md)","id":"CVE-2024-43661","markdown":"https://insights.sbomify.com/CVE-2024-43661/index.md","name":"CVE-2024-43661","record":{"aliases":["GHSA-6wxc-jqg3-v947"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"EV charger firmware","requires_auth":"low_privilege","summary":"A buffer overflow in the OCPP service library allows authenticated attackers to cause a persistent denial of service by triggering a crash loop.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DIVD","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/AU:Y/R:I","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"The \u003credacted\u003e.so library, which is used by \u003credacted\u003e, is\nvulnerable to a buffer overflow in the code that handles the deletion\nof certificates. This buffer overflow can be triggered by providing a\nlong file path to the \u003credacted\u003e action of the \u003credacted\u003e.exe CGI binary or\nto the \u003credacted\u003e.sh CGI script. This binary or script will write this\nfile path to \u003credacted\u003e, which is then\nread by \u003credacted\u003e.so\n\nThis issue affects Iocharger firmware for AC models before version 24120701.\n\nLikelihood: Moderate – An attacker will have to find this exploit by\neither obtaining the binaries involved in this vulnerability, or by trial\nand error. Furthermore, the attacker will need a (low privilege)\naccount to gain access to the \u003credacted\u003e.exe CGI binary or \u003credacted\u003e.sh\nscript to trigger the vulnerability, or convince a user with such access\nsend an HTTP request that triggers it.\n\nImpact: High – The \u003credacted\u003e process, which we assume is\nresponsible for OCPP communication, will keep crashing after\nperforming the exploit. This happens because the buffer overflow\ncauses the process to segfault before\n\u003credacted\u003e is removed. This means that,\neven though \u003credacted\u003e is automatically restarted, it will crash\nagain as soon as it tries to parse the text file.\n\nCVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The attack leads to reducred availability of the device (VC:N/VI:N/VA:H). THere is not impact on subsequent systems. (SC:N/SI:N/SA:N). Alltough this device is an EV charger handing significant amounts of power, we do not forsee a safety impact. The attack can be automated (AU:Y). Because the DoS condition is written to disk persistantly, it cannot be recovered by the user (R:I).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Buffer overflow in \u003credacted\u003e.so leads to DoS of OCPP service","id":"CVE-2024-43661","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"Authenticated arbitrary file upload to /tmp/ and /tmp/upload/","id":"CVE-2024-43662"},"packages":[],"prev":{"headline":"Arbitrary file download using \u003credacted\u003e.sh","id":"CVE-2024-43660"},"products":["Iocharger firmware for AC models"],"published":"2025-01-09","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-11","vendors":["Iocharger"]},"summary":"A buffer overflow in the OCPP service library allows authenticated attackers to cause a persistent denial of service by triggering a crash loop.","url":"https://insights.sbomify.com/CVE-2024-43661/"}
