# CVE-2025-64386: HIJACKING OF THE TOKEN AND GAINING ACCESS

- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2025-10-31 · Updated: 2025-11-03

## Affected

- Circutor TCPRS1plus: 1.0.14

## Description

The equipment grants a JWT token for each connection in the timeline, but during an active valid session, a hijacking of the token can be done. This will allow an attacker with the token modify parameters of security, access or even steal the session without the legitimate and active session detecting it. The web server allows the attacker to reuse an old session JWT token while the legitimate session is active.
