  "details": "## Summary ##\n\nAll user accounts authenticate towards a *File Browser* instance with a password. A missing password policy and brute-force protection makes it impossible for administrators to properly secure the authentication process.\n\n## Impact ##\n\nAttackers can mount a brute-force attack against the passwords of all accounts of an instance. Since the application is lacking the ability to prevent users from choosing a weak password, the attack is likely to succeed.\n\n## Vulnerability Description ##\n\nThe application implement a classical authentication scheme using a username and password combination. While employed by many systems, this scheme is quite error-prone and a common cause for vulnerabilities. File Browser\u0027s implementation has multiple weak points:\n\n1. Since the application is missing the capability for administrators to define a password policy, users are at liberty to set trivial and well-known passwords such as `secret` or even ones with only single digit like `1`.\n2. New instances are set up with a default password of `admin` for the initial administrative account. This password is well known and easily guessable. While the documentation advises to change this password, the application does not technically enforce it.\n3. The application does not implement any brute-force protection for the authentication endpoint. Attackers can make as many guesses for a password as the network bandwidth allows.\n\nThe combination of these problems makes it likely, that an attacker will succeed in compromising at least one account in a *File Browser* instance, possibly even one with administrative privileges. The likelihood of such an attack increases substantially for internet-facing instances.\n\n## Proof of Concept ##\n\nThe insecure default credentials are documented on the application\u0027s website:\n\n![image](https://github.com/user-attachments/assets/46c07d99-dc7b-4d6e-ac27-7eb002229201)\n\nThe following HTTP communication shows, that a trivial password of `1` can be configured by a user:\n\n```http hl:17\nPUT /api/users/2 HTTP/1.1\nHost: filebrowser.local:8080\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate, br\nReferer: http://filebrowser.local:8080/settings/profile\nX-Auth: eyJ[...]\nContent-Type: text/plain;charset=UTF-8\nContent-Length: 319\nOrigin: http://filebrowser.local:8080\nConnection: keep-alive\nCookie: auth=eyJ[...]\nX-PwnFox-Color: cyan\nPriority: u=0\n\n{\"what\":\"user\",\"which\":[\"password\"],\"data\":{\"id\":2,\"locale\":\"en\",\"viewMode\":\"mosaic\",\"singleClick\":false,\"perm\":{\"admin\":false,\"execute\":true,\"create\":true,\"rename\":true,\"modify\":true,\"delete\":true,\"share\":true,\"download\":true},\"commands\":[],\"lockPassword\":false,\"hideDotfiles\":false,\"dateFormat\":false,\"password\":\"1\"}}\n\nHTTP/1.1 200 OK\nCache-Control: no-cache, no-store, must-revalidate\nContent-Security-Policy: default-src \u0027self\u0027; style-src \u0027unsafe-inline\u0027;\nContent-Type: text/plain; charset=utf-8\nX-Content-Type-Options: nosniff\nDate: Thu, 27 Mar 2025 08:31:34 GMT\nContent-Length: 7\n\n200 OK\n```\n\nThe missing brute-force protection can easily be tested by repeatedly sending the following request to the application with a tool such as Burp or hydra.\n\n```\nPOST /api/login HTTP/1.1\nHost: filebrowser.local:8080\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate, br\nContent-Type: application/json\nContent-Length: 52\nOrigin: http://filebrowser.local:8080\n\n{\"username\":\"admin\",\"password\":\"myPasswordGuess\",\"recaptcha\":\"\"}\n\nHTTP/1.1 403 Forbidden\nCache-Control: no-cache, no-store, must-revalidate\nContent-Security-Policy: default-src \u0027self\u0027; style-src \u0027unsafe-inline\u0027;\nContent-Type: text/plain; charset=utf-8\nX-Content-Type-Options: nosniff\nDate: Thu, 27 Mar 2025 08:39:48 GMT\nContent-Length: 14\n\n403 Forbidden\n```\n\nAfter sending 3000 bad passwords to the application within a few seconds, a successful authentication is still possible for the account:\n\n```http\nPOST /api/login HTTP/1.1\nHost: filebrowser.local:8080\nUser-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0\nAccept: */*\nAccept-Language: en-US,en;q=0.5\nAccept-Encoding: gzip, deflate, br\nContent-Type: application/json\nContent-Length: 54\nOrigin: http://filebrowser.local:8080\nConnection: keep-alive\n\n{\"username\":\"admin\",\"password\":\"myCorrectPassword\",\"recaptcha\":\"\"}\n\nHTTP/1.1 200 OK\nCache-Control: no-cache, no-store, must-revalidate\nContent-Security-Policy: default-src \u0027self\u0027; style-src \u0027unsafe-inline\u0027;\nContent-Type: text/plain\nDate: Thu, 27 Mar 2025 08:39:58 GMT\nContent-Length: 508\n\neyJ[...]\n```\n\n## Recommended Countermeasures ##\n\nThe application should add an option to define a password policy in its administrative interface which allows to set a minimum length for passwords.\nThe default settings should be in line with the NIST publication SP 800-63B. This means, that now passwords of fewer than 8 characters should ever be allowed by the application.\nWhenever a user sets a new password, the application should verify whether that password is part of a \"known passwords\" list.\n\nThe application should either create a secure and random password for the `admin` account upon initialization or enforce an immediate password change when that user logs in for the first time using the default password.\n\nA brute-force protection needs to be implemented, which limits the allowed amount of authentication attempts per user within a certain timeframe. This implementation should employ *device tokens* to prevent targeted lockout attacks.\n\nIn addition, it would be advisable to allow the integration of the application into and existing *Identity Provider* using protocols like LDAP or OIDC.\n\n## Timeline ##\n\n* `2025-03-27` Identified the vulnerability in version 2.32.0\n* `2025-04-11` Contacted the project\n* `2025-04-29` Vulnerability disclosed to the project\n* `2025-06-25` Uploaded advisories to the project\u0027s GitHub repository\n* `2025-06-26` CVE ID assigned by GitHub\n* `2025-06-29` Fix released in version 2.34.1. 12 minimum characters as default has been chosen since the implementation does not include protection against brute force attacks. \n\n## References ##\n\n* [OWASP Authentication Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/Authentication_Cheat_Sheet.html#implement-proper-password-strength-controls)\n* [NIST Special Publication 800-63B.

  "details": "## Summary\n\nThe forced password-change flow, triggered when the stored password is still the default (`admin`), does not verify that the password submitted by the client actually matches the current password. Any non-empty value in `pheditor_password` is enough to reach the password-change form, and submitting `pheditor_new_password` / `pheditor_confirm_password` in the same request is enough to set an arbitrary new password and obtain an authenticated session \u2014 without ever proving knowledge of the current password.\n\n## Root Cause\n\n`pheditor.php` line 163:\n\n```php\nif (PASSWORD == hash(\u0027sha512\u0027, \u0027admin\u0027)) { // still default \u2014 force change prompt\n```\n\nThis checks whether the **stored** `PASSWORD` constant is still the default value. It does not check whether the **submitted** `pheditor_password` matches it. As a result, on any instance that hasn\u0027t changed the default password, the check passes regardless of what the client actually sends, and the subsequent password-change branch is reachable without authentication.\n\n## PoC\n\n```bash\nTARGET=\"https://victim.com/pheditor.php\"\n\n# Any non-empty value works here \u2014 password is never actually verified\ncurl -c /tmp/j.txt \\\n  -d \u0027pheditor_password=anything\u0027 \\\n  -d \u0027pheditor_new_password=attacker123\u0027 \\\n  -d \u0027pheditor_confirm_password=attacker123\u0027 \\\n  \"$TARGET\" -L -s -o /dev/null\n\n# Session is now authenticated as admin, with the password changed to attacker123\n```\n\n## Impact\n\nOn any instance where the default password has not yet been changed, an unauthenticated attacker can set an arbitrary new admin password and obtain a fully authenticated session, without knowing the current password. This is a complete authentication bypass, not merely \"default credentials in use\" \u2014 it holds even if the operator believes the instance is protected because the login form is present.\n\n## Remediation\n\nVerify the submitted password against the stored `PASSWORD` constant *before* entering the forced password-change branch, so the flow is reachable only by someone who actually knows the current password:\n\n```php\n$submitted_hash = hash(\u0027sha512\u0027, $_POST[\u0027pheditor_password\u0027]);\n\nif (PASSWORD == hash(\u0027sha512\u0027, \u0027admin\u0027) \u0026\u0026 $submitted_hash === PASSWORD) {\n    // proceed to forced password-change flow\n} else {\n    // treat as a normal login attempt (including rate-limiting)\n}\n```\n\n## Note on scope\n\nThe original report submitted alongside this finding also included two additional items:\n\n- **Unrestricted PHP upload** \u2014 addressed as intended behavior (Pheditor is a single-admin PHP file editor; PHP file creation/editing is core to its function, and pattern-restricting only the upload path doesn\u0027t reduce risk since the same result is reachable via the `save`/`newfile` action). Documented explicitly in the README\u0027s new Security Model section.\n- **Terminal allowlist bypass (`php -r ...`)** \u2014 a duplicate of a previously reported and already-patched issue (GHSA-g3hq-hphg-8fhh, fixed in v2.0.7).\n\nThis advisory has been scoped to the authentication bypass specifically, since it\u0027s a distinct root cause from both of those. Full responses to all three points are in the comments below.",
