CVE-2024-39727Network attack vector

Browser redirection via exposed window.opener access

Published Dec 25, 2024 · Updated Dec 26, 2024

Reverse tabnabbing in IBM Engineering Lifecycle Optimization - Engineering Insights 7.0.2 and 7.0.3 allows remote attackers to redirect users. Links to untrusted external sites open a new tab without preventing the destination from changing security-sensitive window.opener properties such as location. A user must follow an affected link, after which attacker-controlled script on the destination can replace the original tab with a phishing page and expose entered data.
