Description: Injection vulnerability in Cisco ISE API enabling unauthenticated RCE. Technical Details: CVSS Score: 10.0 (Critical) Exploit: Attackers submit crafted POST requests to /admin/XXX endpoints with malicious JSON payloads ({“command”:”exec”}), exploiting insufficient input validation to execute code with root privileges. Bobby Gould’s PoC showed unsafe deserialization in JSON inputs, enabling RCE from Chinese IPs (e.g.,… Read More »CVE-2025-20281 (Cisco ISE)
Description: Vulnerability enabling administrator takeover via XML-based exploits. Technical Details: CVSS Score: 9.2 (Critical) Exploit: Attackers exploit weak XML validation to inject payloads that modify role_id fields (<user><role_id>admin</role_id></user>), escalating to admin privileges. The attack targets /api/v1/admin endpoints, chaining with CVE-2025-2775 for initial data access. Persistence is achieved via modified user accounts with SSH keys added… Read More »CVE-2025-2776 (SysAid On-Prem)
Description: Deserialization vulnerability enabling unauthenticated RCE via the /_layouts/15/ToolPane.aspx endpoint. Technical Details: CVSS Score: 9.8 (Critical) Exploit: Attackers craft malicious ASPX payloads (spinstall0.aspx) to exploit unsafe deserialization, extracting ValidationKey and DecryptionKey from __VIEWSTATE. Spoofed Referer headers (/layouts/SignOut.aspx) bypass authentication. The exploit chains with CVE-2025-49704 (spoofing, CVSS 8.8) and CVE-2025-49706 (RCE bypass), deploying .dll payloads (SHA256:… Read More »CVE-2025-53770 (Microsoft SharePoint)
