Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A stack-based buffer overflow in `unique_service_name` within `ssdp/ssdp_server.c`. π **Consequences**: Remote attackers can execute arbitrary code via long UDN fields in UDP packets.β¦
π‘οΈ **CWE**: Stack-based Buffer Overflow. π **Flaw**: The `unique_service_name` function in the SSDP parser fails to properly validate input length, allowing overflow.β¦
π¦ **Affected**: UPnP Devices (aka libupnp, formerly Intel SDK for UPnP Devices). π **Version**: Specifically **1.3.1**. π Components: Portable SDK for UPnP Devices. β οΈ Check your UPnP stack version!
Q4What can hackers do? (Privileges/Data)
π» **Privileges**: Arbitrary Code Execution. π΅οΈ **Impact**: Remote attackers can run malicious code on the target system. π Data integrity and confidentiality are at risk.β¦
π **Threshold**: LOW. π‘ **Auth**: None required. π **Config**: Exploitable via UDP packets. π Remote exploitation is possible without user interaction or login. β‘ High accessibility for attackers.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: No specific PoC code listed in the `pocs` array. π’ **References**: Vendor advisories exist (Debian DSA-2614, Cisco, Mandriva).β¦
π **Self-Check**: Scan for UPnP services using libupnp v1.3.1. π‘ Look for SSDP responses with unusually long UDN fields. π οΈ Use network scanners to detect UPnP devices.β¦
π§ **No Patch?**: Disable UPnP services if possible. π Block UDP traffic related to SSDP at the firewall. π« Restrict network access to UPnP devices. π Reduce attack surface by limiting exposure.β¦
π₯ **Urgency**: HIGH. π¨ **Priority**: Critical. β‘ Remote Code Execution (RCE) without auth is a top-tier threat. π Published in 2013, but legacy systems may still be vulnerable.β¦
