CVE-2011-0500 in VideoSpirit Pro
Summary
by MITRE
Buffer overflow in VideoSpirit Pro 1.6.8.1, 1.68, and earlier; and VideoSpirit Lite 1.4.0.1 and possibly other versions; allows user-assisted remote attackers to execute arbitrary code via a VideoSpirit project (.visprj) file containing a valitem element with a long "value" attribute, as demonstrated using a valitem with the mp3 name.

The vulnerability identified as CVE-2011-0500 represents a critical buffer overflow flaw affecting VideoSpirit Pro and Lite software versions up to 1.6.8.1 and 1.4.0.1 respectively. This issue stems from inadequate input validation within the software's handling of project files, specifically when processing the valitem element within .visprj files. The flaw manifests when a maliciously crafted project file contains a valitem element with an excessively long value attribute, enabling attackers to exploit the vulnerability through user-assisted remote execution scenarios.
The technical implementation of this vulnerability resides in the software's insufficient bounds checking mechanism when parsing the value attribute of valitem elements within VideoSpirit project files. According to CWE-121, this represents a classic stack-based buffer overflow condition where the software fails to properly validate the length of input data before copying it into a fixed-size buffer. The vulnerability operates under the principle that the application does not enforce adequate size limitations on user-supplied data, allowing an attacker to overwrite adjacent memory locations and potentially execute arbitrary code with the privileges of the affected application.
The operational impact of CVE-2011-0500 extends beyond simple code execution capabilities to encompass broader system compromise potential. Attackers can leverage this vulnerability through social engineering tactics, tricking users into opening maliciously crafted VideoSpirit project files. The attack vector requires user interaction since the exploit is triggered during normal file opening procedures, making it particularly dangerous in environments where users frequently handle multimedia project files. This vulnerability aligns with ATT&CK technique T1203 by enabling code execution through application vulnerabilities, and T1068 by exploiting local application flaws for privilege escalation.
Mitigation strategies for this vulnerability should prioritize immediate software updates and patches from the vendor, as the flaw affects multiple versions of the VideoSpirit product line. System administrators should implement strict file validation policies and consider restricting user access to potentially malicious file types. Network segmentation and application whitelisting can provide additional defense layers, while regular security assessments should verify that all multimedia applications are running patched versions. Organizations should also consider deploying endpoint protection solutions that can detect and block suspicious file execution patterns. The vulnerability demonstrates the critical importance of input validation in multimedia applications and highlights the need for robust buffer management practices in software development processes.
