--- type: Article title: "NoScript (2.0.5.1 < less ) - Bypass \"Reflective XSS\" through Union SQL Poisoning Trick (SQLXSSI)" description: An advisory reporting that NoScript up to 2.0.5.1 fails to flag reflected XSS when the payload arrives through a SQL UNION injection. Hex-encoding the script in a union SELECT column means the request never carries recognisable markup, so the filter passes it while the database reflects it back as live HTML; 2.0.6 remained vulnerable. resource: "https://groups.google.com/g/null-co-in/c/l4-fm9IHtJI" tags: [article, webseclist-reference, en-US, google-groups, xss, sqli, filter-bypass, browser-extension, injection, waf-bypass, vendor-advisory, owasp-a03-2021, owasp-a05-2021] generated: by: webseclist-refs/1 at: "2026-08-11T17:35:24+00:00" status: stable stale_after: 2027-08-11 sources: - id: original resource: "https://groups.google.com/g/null-co-in/c/l4-fm9IHtJI" title: "NoScript (2.0.5.1 < less ) - Bypass \"Reflective XSS\" through Union SQL Poisoning Trick (SQLXSSI)" author: Rohit Bansal also_at: [] authors: - Rohit Bansal canonical_url: "" cited_by: - "2010.md:62" commit: "" content_sha256: e7b11f8cf56461c355da7d41abae9853cd221bc56176ad5b4d9bd094d17f2612 depth: full depth_reason: default kind: article language: en-US licence: unknown original_url: "https://groups.google.com/g/null-co-in/c/l4-fm9IHtJI" published: "" publisher: Google Groups publisher_english: "" raw_sha256: 695601b4ac660cb294657795b081366f756b8470e52c66a5139871b8214f5caa retrieved_from: "https://groups.google.com/g/null-co-in/c/l4-fm9IHtJI" retrieved_kind: stored retrieved_utc: "2026-08-11T17:35:24+00:00" slug: google-groups-noscript-2-0-5-1-less-bypass-reflective-xss-through-union-sqlxssi snapshot: "" title_english: "" translation_file: "" translation_of: "" --- # NoScript (2.0.5.1 < less ) - Bypass "Reflective XSS" through Union SQL Poisoning Trick (SQLXSSI) **NoScript (2.0.5.1 < less ) - Bypass "Reflective XSS" through Union SQL Poisoning Trick (SQLXSSI)** - Rohit Bansal, Google Groups. - Published: date not stated - Original: - Preserved from: https://groups.google.com/g/null-co-in/c/l4-fm9IHtJI (stored) on 2026-08-11 - Licence: unknown Rights remain with the original author and publisher.

The bypass in NoScript has been successfully conducted by using "Reflective XSS" through Union SQL poisoning attacks by exploiting the reverted errors in the browser. The attack string used to bypass is stated below [http://www.example.com/news.php?news=12%27union%20select%201,2,3,4,5,6,7,0x3c7363726970743e616c657274282f73636861702f293c2f7363726970743e,9,10,11,12,version%28%29%20from%20tbl_news--](http://www.example.com/news.php?news=12%27union%20select%201,2,3,4,5,6,7,0x3c7363726970743e616c657274282f73636861702f293c2f7363726970743e,9,10,11,12,version%28%29%20from%20tbl_news--+) The attacker can create a potential attack patterns using the above stated vector. The exploitation video has been released at SecNiche Security channel - [http://www.youtube.com/watch?v=r-kgKNspqjQ](http://www.youtube.com/watch?v=r-kgKNspqjQ) Disclosure: The bug was disclosed to the author on 24th November 2010. A new version of NoScript 2.0.6 is released today (25th November 2010). Further, NoScript 2.0.6 version fails to combat against this attack vector and can be bypassed with the same.
