Impact: Potential ReDOS vulnerabilities (exponential and polynomial RegEx backtracking)

oswasp:

The Regular expression Denial of Service (ReDoS) is a Denial of Service attack, that exploits the fact that most Regular Expression implementations may reach extreme situations that cause them to work very slowly (exponentially related to input size). An attacker can then cause a program using a Regular Expression to enter these extreme situations and then hang for a very long time.

If are you are using Highlight.js to highlight user-provided data you are possibly vulnerable. On the client-side (in a browser or Electron environment) risks could include lengthy freezes or crashes... On the server-side infinite freezes could occur... effectively preventing users from accessing your app or service (ie, Denial of Service).

This is an issue with grammars shipped with the parser (and potentially 3rd party grammars also), not the parser itself. If you are using Highlight.js with any of the following grammars you are vulnerable. If you are using highlightAuto to detect the language (and have any of these grammars registered) you are vulnerable. Exponential grammars (C, Perl, JavaScript) are auto-registered when using the common grammar subset/library require('highlight.js/lib/common') as of 10.4.0 - see https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@10.4.0/build/highlight.js

All versions prior to 10.4.1 are vulnerable, including version 9.18.5.

Grammars with exponential backtracking issues:

• c-like (c, cpp, arduino)
• handlebars (htmlbars)
• gams
• perl
• jboss-cli
• r
• erlang-repl
• powershell
• routeros
• livescript (10.4.0 and 9.18.5 included this fix)
• javascript & typescript (10.4.0 included partial fixes)

And of course any aliases of those languages have the same issue. ie: hpp is no safer than cpp.

Grammars with polynomial backtracking issues:

• kotlin
• gcode
• d
• aspectj
• moonscript
• coffeescript/livescript
• csharp
• scilab
• crystal
• elixir
• basic
• ebnf
• ruby
• fortran/irpf90
• livecodeserver
• yaml
• x86asm
• dsconfig
• markdown
• ruleslanguage
• xquery
• sqf

And again: any aliases of those languages have the same issue. ie: ruby and rb share the same ruby issues.

Patches

• Version 10.4.1 resolves these vulnerabilities. Please upgrade.

Workarounds / Mitigations

• Discontinue use the affected grammars. (or perhaps use only those with poly vs exponential issues)
• Attempt cherry-picking the grammar fixes into older versions...
• Attempt using newer CDN versions of any affected languages. (ie using an older CDN version of the library with newer CDN grammars). Your mileage may vary.

v10.3.2: - Oops, "Javascript".

Compare Source

Tiny tiny release, just to fix the website incorrectly not listing Javascript
in the list of languages you could choose for a custom build. NPM and CDN
build should not have been affected so 10.3.1 is effectively the same as
10.3.2 for those builds.

If you made a custom build from the website with 10.3 or 10.3.1 you may
want to check and make sure it includes Javascript, and if not, build it again.
