Modx : Security Vulnerabilities, CVEs, (Denial of service)

A XML External Entity (XXE) vulnerability was discovered in the modRestServiceRequest component in MODX CMS 2.7.3 which can lead to an information disclosure or denial of service (DOS).

setup/controllers/language.php in MODX Revolution 2.5.4-pl and earlier does not properly constrain the language parameter, which allows remote attackers to conduct Cookie-Bombing attacks and cause a denial of service (cookie quota exhaustion), or conduct HTTP Response Splitting attacks with resultant XSS, via an invalid parameter value.
