An anonymous reader writes from a report via Softpedia: "Researcher Jerry Decime revealed details about a security vulnerability that allows an attacker to gain a Man-in-the-Middle position and intercept HTTPS traffic thanks to flaws in the implementation of proxy authentication procedures in various products," reports Softpedia. The flaw can be used to collect user credentials by tricking victims into re-authenticating, sending data to a third-party. Multiple software vendors deploy applications that can handle proxy connections. Until now, Apple, Microsoft, Oracle, and Opera have acknowledged their products are affected. Lenovo said this bug does not impact its software. Other software vendors that are still evaluating the FalseCONNECT bug and may be affected include multiple Linux distros, Cisco, Google, HP, IBM, Juniper, Mozilla, Nokia, OpenBSD, SAP, Sony, and others.
