Summary
Kiloview E3 NDI Encoder firmware before 1.30 issues web management interface authentication tokens with an expiration time far beyond any reasonable session lifetime, so they never expire. A token obtained through interception or device compromise stays valid for authenticated access for an extended period, which relates to CWE-613.

Description from the CNA
Authentication tokens issued by the E3's web management interface on login are given an expiration time far beyond any reasonable session lifetime, effectively making them non-expiring. A token obtained through interception or device compromise remains valid for authenticated access for an extended period.
