#vulnerability

### Impact KaTeX users who render untrusted mathematical expressions could encounter malicious input using `\includegraphics` that runs arbitrary JavaScript, or generate invalid HTML. ### Patches Upgrade to KaTeX v0.16.10 to remove this vulnerability. ### Workarounds * Avoid use of or turn off the `trust` option, or set it to forbid `\includegraphics` commands. * Forbid inputs containing the substring `"\\includegraphics"`. * Sanitize HTML output from KaTeX. ### Details `\includegraphics` did not properly quote its filename argument, allowing it to generate invalid or malicious HTML that runs scripts. ### For more information If you have any questions or comments about this advisory: * Open an issue or security advisory in the [KaTeX repository](https://github.com/KaTeX/KaTeX/) * Email us at [email protected]

### Impact KaTeX users who render untrusted mathematical expressions could encounter malicious input using `\def` or `\newcommand` that causes a near-infinite loop, despite setting `maxExpand` to avoid such loops. This can be used as an availability attack, where e.g. a client rendering another user's KaTeX input will be unable to use the site due to memory overflow, tying up the main thread, or stack overflow. ### Patches Upgrade to KaTeX v0.16.10 to remove this vulnerability. ### Workarounds Forbid inputs containing any of the characters `₊₋₌₍₎₀₁₂₃₄₅₆₇₈₉ₐₑₕᵢⱼₖₗₘₙₒₚᵣₛₜᵤᵥₓᵦᵧᵨᵩᵪ⁺⁻⁼⁽⁾⁰¹²³⁴⁵⁶⁷⁸⁹ᵃᵇᶜᵈᵉᵍʰⁱʲᵏˡᵐⁿᵒᵖʳˢᵗᵘʷˣʸᶻᵛᵝᵞᵟᵠᵡ` before passing them to KaTeX. (There is no easy workaround for the auto-render extension.) ### Details KaTeX supports an option named `maxExpand` which aims to prevent infinitely recursive macros from consuming all available memory and/or triggering a stack overflow error. Unfortunately, [support for "Unicode (sub|super)script characters"](https://github.com/KaTeX/...

### Impact KaTeX users who render untrusted mathematical expressions could encounter malicious input using `\edef` that causes a near-infinite loop, despite setting `maxExpand` to avoid such loops. This can be used as an availability attack, where e.g. a client rendering another user's KaTeX input will be unable to use the site due to memory overflow, tying up the main thread, or stack overflow. ### Patches Upgrade to KaTeX v0.16.10 to remove this vulnerability. ### Workarounds Forbid inputs containing the substring `"\\edef"` before passing them to KaTeX. (There is no easy workaround for the auto-render extension.) ### Details KaTeX supports an option named `maxExpand` which prevents infinitely recursive macros from consuming all available memory and/or triggering a stack overflow error. However, what counted as an "expansion" is a single macro expanding to any number of tokens. The expand-and-define TeX command `\edef` can be used to build up an exponential number of tokens using ...

## Summary A security vulnerability exists in oneuptime's local storage handling, where a regular user can escalate privileges by modifying the `is_master_admin` key to `true`. This allows unauthorized access to administrative functionalities. ## Details The vulnerability lies in the improper validation of client-side stored data within the web application. Specifically, the `is_master_admin` key, stored in the local storage of the browser, can be manipulated by an attacker. By changing this key from false to true, the application grants administrative privileges to the user, without proper server-side validation. ## POC (I am using Firefox Developer to demonstrate this vulnerability) Log in as a normal user. Open developer tools (hit F12), click Storage, then Local Storage. Modify the `is_master_admin` key from `false` to `true`. ## Impact This vulnerability represents a high security risk as it allows any authenticated user to gain administrative privileges through client-side ma...

An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby 3.x through 3.3.0. When parsing `.rdoc_options` (used for configuration in RDoc) as a YAML file, object injection and resultant remote code execution are possible because there are no restrictions on the classes that can be restored. When loading the documentation cache, object injection and resultant remote code execution are also possible if there were a crafted cache. We recommend to update the RDoc gem to version 6.6.3.1 or later. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead: * For Ruby 3.0 users: Update to `rdoc` 6.3.4.1 * For Ruby 3.1 users: Update to `rdoc` 6.4.1.1 * For Ruby 3.2 users: Update to `rdoc` 6.5.1.1 You can use `gem update rdoc` to update it. If you are using bundler, please add `gem "rdoc", ">= 6.6.3.1"` to your `Gemfile`. Note: 6.3.4, 6.4.1, 6.5.1 and 6.6.3 have a incorrect fix. We recommend to upgrade 6.3.4.1, 6.4.1.1, ...

An issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The `ungetbyte` and `ungetc` methods on a StringIO can read past the end of a string, and a subsequent call to `StringIO.gets` may return the memory value. This vulnerability is not affected StringIO 3.0.3 and later, and Ruby 3.2.x and later. We recommend to update the StringIO gem to version 3.0.3 or later. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead: * For Ruby 3.0 users: Update to `stringio` 3.0.1.1 * For Ruby 3.1 users: Update to `stringio` 3.1.0.2 You can use `gem update stringio` to update it. If you are using bundler, please add `gem "stringio", ">= 3.0.1.2"` to your `Gemfile`.

### Summary There is a Path Traversal vulnerability in Attachments that allows attackers with admin rights to upload malicious files to other locations of the web root. ### PoC 1. In settings, the attachment location is vulnerable to path traversal and can be set to e.g ..\hacked  2. When the above is set, attachments files are now uploaded to e.g C:\Apps\XAMPP\htdocs\hacked instead of C:\Apps\XAMPP\htdocs\phpmyfaq\attachments 3. Verify this by uploading an attachment and see that the "hacked" directory is now created in the web root folder with the attachment file inside.   ### Impact Attackers can potentially upload malicious files outside the specified directory.
