A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to bypass authorization, enabling them to access sensitive information, modify the system configuration, or impact the availability of the affected system. The vulnerability is due to insufficient authorization checking on the affected system. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based management interface of an affected system. A successful exploit could allow the attacker to gain privileges beyond what would normally be authorized for their configured user authorization level. The attacker may be able to access sensitive information, modify the system configuration, or impact the availability of the affected system.

Detection & IOCsextracted from sources · hover to see the quote
- →Detect crafted HTTP requests sent to the Cisco SD-WAN vManage web-based management interface that attempt to bypass authorization checks, potentially accessing endpoints beyond the user's configured authorization level. ↗
- →Monitor for authenticated users accessing resources or performing actions (sensitive data access, configuration modification) inconsistent with their configured user authorization level on vManage. ↗
- ·The vulnerability is due to insufficient authorization checking on the affected system (CWE-285: Improper Authorization). Exploitation requires an authenticated session — unauthenticated access is not sufficient. ↗
- ·No workarounds are available; detection and mitigation rely on patching. Track Cisco Bug ID CSCvs39776 for patch status. ↗
