CVE-2010-2882 in Shockwave Player
Summary
by MITRE
DIRAPI.dll in Adobe Shockwave Player before 11.5.8.612 does not properly parse .dir files, which allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via a malformed file containing an invalid value, as demonstrated by a value at position 0x3812 of a certain file.

Adobe Shockwave Player DIRAPI.dll component contains a critical buffer overflow vulnerability that arises from improper parsing of .dir files. This vulnerability exists in versions prior to 11.5.8.612 and represents a classic stack-based buffer overflow scenario where maliciously crafted input data exceeds the allocated memory buffer boundaries. The flaw specifically manifests when processing a malformed .dir file containing an invalid value at position 0x3812, which triggers memory corruption during the parsing operation. This vulnerability falls under CWE-121, stack-based buffer overflow, and aligns with ATT&CK technique T1203 for legitimate program exploitation. The vulnerability allows remote attackers to execute arbitrary code on affected systems or cause denial of service conditions through memory corruption, making it particularly dangerous in web browsing environments where .dir files might be automatically processed. The technical implementation involves the DIRAPI.dll library failing to validate input parameters before copying data into fixed-size buffers, enabling attackers to overwrite adjacent memory locations with malicious payloads. This type of vulnerability is classified as a remote code execution threat that can be exploited through web-based attacks, potentially allowing attackers to gain full system control.
The operational impact of this vulnerability extends beyond simple denial of service to include complete system compromise capabilities. When a user visits a malicious website or opens a specially crafted .dir file, the vulnerable Shockwave Player component processes the malformed data and triggers the buffer overflow condition. The memory corruption at position 0x3812 can overwrite critical program execution structures including return addresses, function pointers, or other control data, enabling attackers to redirect program flow and execute arbitrary code with the privileges of the affected user. This vulnerability affects a wide range of Adobe Shockwave Player installations and represents a significant risk to enterprise environments where Shockwave content is commonly used for multimedia applications, interactive games, and business presentations. The exploitation mechanism is particularly concerning because it requires no user interaction beyond visiting a malicious webpage, making it a prime candidate for drive-by download attacks and social engineering campaigns. The vulnerability's impact is amplified by the widespread deployment of Shockwave Player across various operating systems and platforms, including windows systems where Adobe Shockwave was commonly installed.
Mitigation strategies for this vulnerability must include immediate patching of affected systems to upgrade to Adobe Shockwave Player version 11.5.8.612 or later, which contains the necessary fixes for the buffer overflow condition. Organizations should implement network-based security controls such as web application firewalls and content filtering systems to prevent access to known malicious domains hosting exploit code. Additionally, security administrators should disable Shockwave Player plugins in web browsers where possible, as this reduces the attack surface for remote exploitation attempts. The implementation of application whitelisting policies can further restrict execution of untrusted Shockwave content, while regular security assessments should verify that no vulnerable versions remain installed on enterprise systems. System monitoring should be enhanced to detect unusual memory allocation patterns or process behavior that might indicate exploitation attempts. Security teams should also consider implementing sandboxing techniques for handling untrusted Shockwave content and establish incident response procedures specifically addressing remote code execution vulnerabilities. Regular vulnerability scanning and patch management processes should prioritize this vulnerability due to its high severity classification and potential for automated exploitation. The remediation process must include comprehensive testing of patched versions to ensure that the security fixes do not introduce compatibility issues with existing Shockwave-based applications. Organizations should also conduct security awareness training to educate users about the risks of visiting untrusted websites and opening unknown file attachments that might contain malicious Shockwave content.
