Escape sequence injection vulnerability in the Basic authentication of WEBrick

There is an escape sequence injection vulnerability in the Basic authentication of WEBrick bundled by Ruby. When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject...

RubyGems: Escape sequence injection in "summary" field

Seems we can include any escape sequence in the "summary" field of gemspec. This allows attackers to inject escape sequences to a victim's terminal emulator. How to attack 1 An attacker creates a gem with summary string that includes malicious escape sequences, and push it to rubygems.org. 2 A...
