CVE-2018-15542
The Passcode feature allows authentication bypass via runtime manipulation that forces a certain method's return value to true.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in the org.telegram.messenger application 4.8.11 for Android. The Passcode feature allows authentication bypass via runtime manipulation that forces a certain method's return value to true. In other words, an attacker could authenticate with an arbitrary passcode. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred
