4.3
CVSS v3.1
Official Description
The RSA-CRT implementation in PolarSSL before 1.2.9 does not properly perform Montgomery multiplication, which might allow remote attackers to conduct a timing side-channel attack and retrieve RSA private keys.
Technical Analysis
CVE-2013-5915 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
