What is CVE-2019-9153?
The vulnerability in OpenPGP.js arises from improper verification of cryptographic signatures, enabling attackers to forge signed messages. By manipulating either a 'standalone' or 'timestamp' signature, an attacker can replace legitimate signatures, thus compromising message integrity. This active exploitation poses risks for applications relying on OpenPGP.js for secure communications. It is crucial to address this vulnerability by updating to the latest version, which includes mitigations against these types of signature replacements.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
