#xss

A cross-site scripting (XSS) vulnerability in the component /blog/blogpost/add of Mezzanine CMS v6.1.0 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into a blog post.

XSS.IS has been seized after its admin was arrested in Ukraine, however its dark web and mirror domains only show a 504 Gateway Timeout error.

### Summary The regular expression patched to mitigate the ReDoS vulnerability by limiting the length of string fails to catch inputs that exceed this limit. ### Details In version 3.0.1, you can find a commit like the one in the link below, which was made to prevent ReDoS. https://github.com/rennf93/fastapi-guard/commit/d9d50e8130b7b434cdc1b001b8cfd03a06729f7f This commit mitigates the vulnerability by limiting the length of the input string, as shown in the example below. `r"<script[^>]*>[^<]*<\\/script\\s*>"` -> `<script[^>]{0,100}>[^<]{0,1000}<\\/script\\s{0,10}>` This type of patch fails to catch cases where the string representing the attributes of a <script> tag exceeds 100 characters. Therefore, most of the regex patterns present in version 3.0.1 can be bypassed. ### PoC 1. clone the fastapi-guard repository 2. Navigate to the examples directory and modify the main.py source code. Change the HTTP method for the root route from GET to POST. <img width="1013" height="554" ...

### Summary The NodeJS version of HAX CMS has a disabled Content Security Policy (CSP). This configuration is insecure for a production application because it does not protect against cross-site-scripting attacks. ### Details The `contentSecurityPolicy` value is explicitly disabled in the application's Helmet configuration in `app.js`.  #### Affected Resources - [app.js:52](https://github.com/haxtheweb/haxcms-nodejs/blob/b1f95880b42fea6ed07855b5804b29b182ec5e07/src/app.js#L52) ### PoC To reproduce this vulnerability, [install](https://github.com/haxtheweb/haxcms-nodejs) HAX CMS NodeJS. The application will load without a CSP configured. ### Impact In conjunction with an XSS vulnerability, an attacker could execute arbitrary scripts and exfiltrate data, including session tokens and sensitive local data. #### Additional Information - [OWASP: Content Security Policy](https://cheats...
