Описание
Jenkins 2.567 and earlier, LTS 2.555.2 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins when it contains tab or newline characters between //, allowing attackers to perform phishing attacks.
A flaw was found in Jenkins. This vulnerability allows a remote attacker to perform phishing attacks by crafting a malicious redirect URL. The flaw occurs because Jenkins improperly validates redirect URLs after login, specifically when tab or newline characters are present between the // in the URL. This can trick users into visiting malicious sites, potentially leading to credential theft or other security compromises.
