CVE-2007-6149 in Flash Media Server 2
Summary
by MITRE
Multiple integer overflows in the Edge server in Adobe Flash Media Server 2 before 2.0.5, and Connect Enterprise Server 6 before SP3, allow remote attackers to execute arbitrary code via a Real Time Message Protocol (RTMP) message with a crafted integer field that is used for allocation.

The vulnerability identified as CVE-2007-6149 represents a critical security flaw affecting Adobe Flash Media Server 2 versions prior to 2.0.5 and Connect Enterprise Server 6 versions prior to SP3. This issue stems from multiple integer overflow conditions within the Edge server component that processes Real Time Message Protocol messages. The flaw specifically targets the allocation mechanisms used when handling RTMP communications, creating a pathway for remote code execution through carefully crafted malicious input.
The technical implementation of this vulnerability involves integer overflow conditions that occur when processing RTMP message fields used for memory allocation operations. When an attacker sends a specially crafted RTMP message containing manipulated integer values, these values can cause arithmetic overflow during allocation calculations. This overflow results in improper memory handling where the system attempts to allocate memory blocks of incorrect sizes, potentially leading to buffer overflows or memory corruption. The vulnerability manifests in the server's handling of message parameters that are directly used to determine memory allocation sizes, making it particularly dangerous as it operates at the core memory management level of the application.
From an operational perspective, this vulnerability presents a severe risk to organizations relying on Adobe Flash Media Server infrastructure, as it enables remote attackers to execute arbitrary code without authentication. The impact extends beyond simple privilege escalation to potentially allow complete system compromise, data exfiltration, and service disruption. Attackers can leverage this vulnerability to gain unauthorized access to media server environments, potentially leading to unauthorized content distribution, server takeover, or use as a foothold for further network infiltration. The remote nature of the attack means that exploitation can occur from anywhere on the internet without requiring physical access or prior authentication.
The vulnerability aligns with CWE-190, which specifically addresses integer overflow conditions, and demonstrates characteristics consistent with ATT&CK technique T1059.007 for command and scripting interpreter, as successful exploitation would likely involve executing arbitrary code through the compromised server. Organizations should implement immediate mitigations including applying the vendor patches released for Adobe Flash Media Server 2.0.5 and Connect Enterprise Server 6 SP3, along with network-level restrictions preventing unauthorized RTMP traffic. Additionally, monitoring for unusual RTMP message patterns and implementing intrusion detection systems can help identify potential exploitation attempts. The remediation process should also include comprehensive security assessments of all media server implementations to ensure complete patch coverage and proper configuration management to prevent similar vulnerabilities in other components of the media streaming infrastructure.
