{"id":"CVE-2024-24767","aliases":["GHSA-c69x-5xmw-v44x","GO-2024-2614"],"url":"https://o3.security/vulnerability/CVE-2024-24767","summary":"CasaOS Improper Restriction of Excessive Authentication Attempts vulnerability","details":"### Summary\nHere it is observed that the CasaOS doesn't defend against password brute force attacks, which leads to having full access to the server.\n\n### Details\nThe web application lacks control over the login attempts i.e. why attacker can use a password brute force attack to find and get full access over the.\n\n### PoC\n1. Capture login request in proxy tool like Burp Suite and select password field.\n\n![1](https://user-images.githubusercontent.com/63414468/297156515-0272bfd7-f386-4c22-b3bd-c4dbdc1298bf.PNG)\n\n2. Here I have started attack with total number of 271 password tries where the last one is the correct password and as we can see in the following image we get a **400 Bad Request** status code with the message \"**Invalid Password**\" and response length **769** on 1st request which was sent at **_Tue, 16 Jan 2024 18:31:32 GMT_**\n\n![2](https://user-images.githubusercontent.com/63414468/297157815-c158995b-7d46-4a5a-aef9-bcbbcf596b15.png)\n\n**Note**:  _We have tested this vulnerability with more than 3400 tries. We have used 271 request counts just for demo purposes._\n\n\n3. Here the attack is completed and we can see in the following image we get **200 OK** status code with the message \"**Ok**\" and response length **1509** on 271st request which was sent at **_Tue, 16 Jan 2024 18:32:01 GMT_**.\n\n![3](https://user-images.githubusercontent.com/63414468/297159282-3f4788b5-6217-4f32-8be6-40ac117710e3.png)\n\nThis means attacker can try 271 requests in 56 seconds.\n\n### Impact\nThis vulnerability allows attackers to get super user-level access over the server.\n\n\n### Mitigation\nIt is recommended to implement a proper rate-limiting mechanism on the server side where the configuration might be like:\nIf a specific IP address fails to login more than 5 times concurrently then that IP address must be blocked for at least 30 seconds. This will reduce the possibility of password brute-forcing attacks.","published":"2024-03-06T18:06:26.237Z","modified":"2026-10-28T02:30:23.382880549Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/IceWhaleTech/CasaOS-UserService","fixedVersion":"0.4.7"}],"fix":{"url":"https://github.com/IceWhaleTech/CasaOS-UserService/commit/62006f61b55951048dbace4ebd9e483274838699","label":"IceWhaleTech/CasaOS-UserService@62006f6"},"references":[{"type":"WEB","url":"https://github.com/IceWhaleTech/CasaOS-UserService/releases/tag/v0.4.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/24xxx/CVE-2024-24767.json"},{"type":"ADVISORY","url":"https://github.com/IceWhaleTech/CasaOS-UserService/security/advisories/GHSA-c69x-5xmw-v44x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-24767"},{"type":"FIX","url":"https://github.com/IceWhaleTech/CasaOS-UserService/commit/62006f61b55951048dbace4ebd9e483274838699"},{"type":"PACKAGE","url":"https://github.com/IceWhaleTech/CasaOS-UserService"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2024-2614"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:23.382880549Z"}}
