CVSS: 5.0EPSS: 0%CPEs: 1EXPL: 0CVE-2024-23336 – Incomplete disallowed remote addresses list in MyBB
https://notcve.org/view.php?id=CVE-2024-23336
MyBB is a free and open source forum software. The default list of disallowed remote hosts does not contain the `127.0.0.0/8` block, which may result in a Server-Side Request Forgery (SSRF) vulnerability. The Configuration File's _Disallowed Remote Addresses_ list (`$config['disallowed_remote_addresses']`) contains the address `127.0.0.1`, but does not include the complete block `127.0.0.0/8`. MyBB 1.8.38 resolves this issue in default installations. Administrators of installed boards should update the existing configuration (`inc/config.php`) to include all addresses blocked by default. • https://docs.mybb.com/1.8/administration/configuration-file https://github.com/mybb/mybb/commit/d6a96019025de9149014e06b1df252e6122e5630 https://github.com/mybb/mybb/security/advisories/GHSA-qfrj-65mv-h75h https://mybb.com/versions/1.8.38 • CWE-184: Incomplete List of Disallowed Inputs CWE-918: Server-Side Request Forgery (SSRF) •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-46251 – Visual editor persistent Cross-site Scripting (XSS) in MyBB
https://notcve.org/view.php?id=CVE-2023-46251
MyBB is a free and open source forum software. Custom MyCode (BBCode) for the visual editor (_SCEditor_) doesn't escape input properly when rendering HTML, resulting in a DOM-based XSS vulnerability. This weakness can be exploited by pointing a victim to a page where the visual editor is active (e.g. as a post or Private Message) and operates on a maliciously crafted MyCode message. This may occur on pages where message content is pre-filled using a GET/POST parameter, or on reply pages where a previously saved malicious message is quoted. The impact is be mitigated when: 1. the visual editor is disabled globally (_Admin CP → Configuration → Settings → Clickable Smilies and BB Code: [Clickable MyCode Editor](https://github.com/mybb/mybb/blob/mybb_1836/install/resources/settings.xml#L2087-L2094)_ is set to _Off_), or 2. the visual editor is disabled for individual user accounts (_User CP → Your Profile → Edit Options_: _Show the MyCode formatting options on the posting pages_ checkbox is not checked). • https://github.com/mybb/mybb/commit/6dcaf0b4db6254f1833fe8dae295d9ddc2219276 https://github.com/mybb/mybb/security/advisories/GHSA-wj33-q7vj-9fr8 https://mybb.com/versions/1.8.37 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
