Detailsinfo

A vulnerability was found in RealNetworks Helix Server up to 11.1. It has been classified as very critical. Affected is the function AgentX::receive_agentx. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x and other products, allows remote attackers to execute arbitrary code via unspecified vectors.

The weakness was released 04/20/2010 by Manuel Santamarina Suarez (Website). The advisory is shared for download at vupen.com. This vulnerability is traded as CVE-2010-1318. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. The current price for an exploit might be approx. USD (estimation calculated on 04/06/2025). It is expected to see the exploit prices for this product decreasing in the near future.

A public exploit has been developed by ZSploit.com and been published before and not just after the advisory. The exploit is shared for download at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $25k-$100k.
