psychologyCrowdSec Analysis
CVE-2025-22457 is a critical stack-based buffer overflow vulnerability in Ivanti Connect Secure, Policy Secure, and Neurons for ZTA Gateways, allowing remote unauthenticated attackers to execute arbitrary code on affected systems. This flaw could be exploited to gain full control over the targeted devices, potentially leading to data breaches, system compromise, or further attacks within the network.
CrowdSec has been tracking this vulnerability and its exploits since 3rd of September 2025.
CrowdSec network data shows that most actors exploiting CVE-2025-22457 rely on broad, untargeted scans with minimal filtering. The activity is largely automated and opportunistic in nature. In addition, according to the CrowdSec network, attack volume against CVE-2025-22457 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.
Attackers exploit this vulnerability by sending specially crafted HTTP requests with an oversized X-Forwarded-For header to the /dana-na/auth/url_default/welcome.cgi endpoint, aiming to trigger a stack-based buffer overflow and achieve remote code execution.

Related Weaknesses
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
