IBM Sterling Secure Proxy 6.2.0.0 through 6.2.1.2 could allow a remote authenticated attacker to perform UI spoofing and phishing attacks due to improper neutralization of user-supplied HTML markup.
AnalysisAI
Authenticated HTML injection in IBM Sterling Secure Proxy 6.2.0.0 through 6.2.1.2 lets a logged-in user plant unescaped markup in the management interface, so the product renders attacker-controlled content as trusted UI. The result is UI spoofing and phishing: a crafted page can impersonate legitimate Sterling Secure Proxy screens to harvest credentials or trick operators into unsafe actions, with limited confidentiality and integrity impact (CVSS 5.4). …
