Advisory Release Date: 2022-12-01 20:31 Pacific
Advisory Updated Date: 2022-12-06 22:40 Pacific
A denial of service flaw was found in ruby-rack. An attacker crafting multipart POST requests can cause Rack's multipart parser to take much longer than expected, leading to a denial of service. (CVE-2022-30122)
A flaw was found in ruby gem-rack. This flaw allows a malicious actor to craft requests that can cause shell escape sequences to be written to the terminal via rack's `Lint` middleware and `CommonLogger` middleware. This issue can leverage these escape sequences to execute commands in the victim's terminal. (CVE-2022-30123)
