Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A stack-based buffer overflow in `unique_service_name` function within SSDP parser (`ssdp/ssdp_server.c`). π₯ **Consequences**: Remote attackers can execute arbitrary code via long DeviceType fields in UDP β¦
π‘οΈ **Root Cause**: Stack-based buffer overflow. π **Flaw**: The `unique_service_name` function fails to properly handle input length in the SSDP parser, leading to memory corruption.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: UPnP Devices (libupnp / Intel SDK for UPnP Devices). π **Version**: Specifically version **1.3.1** of the portable SDK.
Q4What can hackers do? (Privileges/Data)
π» **Hackers' Power**: Execute **arbitrary code**. π **Privileges**: Gained via remote exploitation through UDP packets. No local access needed.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. π **Auth/Config**: Remote exploitation possible. No authentication required. Attack vector is UDP packets.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public Exp?**: Yes, referenced in security advisories (Cisco, Debian, Mandriva). π **PoC**: Specific PoC code not listed in data, but vendor advisories confirm exploitability (BID 57602).
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for UPnP devices running **libupnp v1.3.1**. π‘ **Feature**: Look for SSDP services. Check if `unique_service_name` handling is vulnerable to oversized DeviceType fields.
π§ **No Patch?**: Disable UPnP services if not needed. π **Mitigation**: Block UDP traffic related to SSDP/UPnP at the firewall. Isolate affected devices.
