CVE-2008-1396
CWE-255Published: March 20, 2008· Updated: Jun 16, 2026
4.3
CVSS v3.1
Official Description
Plone CMS 3.x uses invariant data (a client username and a server secret) when calculating an HMAC-SHA1 value for an authentication cookie, which makes it easier for remote attackers to gain permanent access to an account by sniffing the network.
Technical Analysis
CVE-2008-1396 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.
