Alert meAnalysisAIv1 – Sep 15, 2026
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). No public exploit code has been identified and the flaw is not listed in CISA KEV; the vendor has published a fix, though an exact fixed version is not named in the provided data.
