CVE-2010-2004 in BS.Player
Summary
by MITRE
Stack-based buffer overflow in BS.Global BS.Player 2.51 Build 1022 Free, and possibly other versions, allows user-assisted remote attackers to execute arbitrary code via the Skin parameter in the Options section of a skins file (.bsi), a different vulnerability than CVE-2009-1068.

The vulnerability described in CVE-2010-2004 represents a critical stack-based buffer overflow flaw in BS.Global BS.Player version 2.51 Build 1022 and potentially other iterations of the software. This vulnerability specifically targets the skin parameter handling within the Options section of skin files bearing the .bsi extension, creating a dangerous condition where malicious input can overwrite adjacent memory locations on the stack. The flaw falls under the CWE-121 category of stack-based buffer overflow, which is classified as a serious software weakness that can lead to arbitrary code execution when exploited properly. The vulnerability is distinct from CVE-2009-1068, indicating that this represents a separate attack vector within the same software ecosystem.
The technical implementation of this vulnerability occurs when the BS.Player application processes skin files that contain maliciously crafted skin parameters within their Options section. When the software attempts to parse these parameters without proper bounds checking, it fails to validate the length of input data being written to a fixed-size stack buffer. This allows attackers to overflow the buffer and overwrite return addresses, function pointers, and other critical stack data. The attack requires user interaction since the malicious .bsi file must be loaded by the vulnerable application, making it a user-assisted remote attack rather than a fully autonomous exploit. The overflow can potentially be leveraged to redirect program execution flow and execute malicious code with the privileges of the affected user.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with a means to compromise systems running vulnerable versions of BS.Player. The attack surface is particularly concerning given that media players like BS.Player are frequently used and often run with elevated privileges. Successful exploitation could allow attackers to install malware, steal sensitive data, or establish persistent access to compromised systems. The vulnerability's classification as a stack-based buffer overflow aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as the executed code could potentially spawn command shells or other malicious processes. Additionally, this vulnerability could be leveraged as part of a broader attack chain, potentially serving as an initial access point for more sophisticated compromise techniques.
Mitigation strategies for CVE-2010-2004 should focus on immediate software updates and patches provided by BS.Global, as the vendor would have likely released a fix addressing the buffer overflow in the skin parameter handling. System administrators should implement strict file access controls and user education regarding the dangers of opening untrusted media skin files. Network-based defenses could include filtering .bsi files at network boundaries and implementing application whitelisting policies that restrict execution of vulnerable software. The vulnerability demonstrates the importance of proper input validation and bounds checking in software development, emphasizing the need for secure coding practices that align with OWASP Top Ten security principles. Organizations should also consider implementing sandboxing techniques for media player applications and regularly auditing their software inventory to identify and remediate similar vulnerabilities across their entire infrastructure.
