The Blog post about "Revisiting Cross Session Activation attacks" is now also public. Lateral Movement with code execution in the context of an active session?Here you go.

The described security threat pertains to a vulnerability enabling lateral movement with code execution within the context of active user sessions, as highlighted in a recent blog post referenced on the Reddit NetSec community. This attack vector, termed "Cross Session Activation," allows an attacker to execute code by leveraging active sessions of legitimate users, potentially bypassing traditional authentication and session isolation mechanisms. The technique involves exploiting session management flaws or weaknesses in how session tokens or credentials are handled, enabling an adversary to move laterally across systems within a network without triggering standard authentication alerts. Although detailed technical specifics are limited due to minimal discussion and lack of official patches or CVEs, the core risk lies in the ability to execute arbitrary code under the guise of an active user session, thereby compromising confidentiality, integrity, and availability of affected systems. The absence of known exploits in the wild suggests this is an emerging threat, but the medium severity rating indicates a tangible risk that could be escalated if weaponized effectively. The attack likely targets enterprise environments where session persistence and lateral movement are critical attack phases, especially in networks with insufficient session isolation or monitoring.
