CVE-2010-1688 in SyncBack
Summary
by MITRE
Stack-based buffer overflow in 2BrightSparks SyncBack Freeware 3.2.20.0, and possibly other versions before 3.2.21, allows user-assisted remote attackers to execute arbitrary code via a long filename in a (1) .sps or (2) zip profile.

The vulnerability identified as CVE-2010-1688 represents a critical stack-based buffer overflow flaw affecting 2BrightSparks SyncBack Freeware version 3.2.20.0 and earlier releases. This issue manifests when the application processes specially crafted profile files containing excessively long filenames, creating a dangerous condition that can be exploited by remote attackers. The vulnerability specifically impacts two file formats: .sps profile files and zip profile archives, both of which are commonly used within the synchronization process of the software.
The technical nature of this flaw stems from inadequate input validation mechanisms within the SyncBack Freeware application. When processing profile files containing overly long filenames, the software fails to properly bounds-check the input data before copying it onto the stack. This allows an attacker to overwrite adjacent stack memory locations, potentially corrupting the program's execution flow and enabling arbitrary code execution. The stack-based buffer overflow occurs because the application uses unsafe string handling functions that do not perform sufficient length verification before copying data into fixed-size buffers, creating a classic vulnerability pattern that aligns with CWE-121 stack-based buffer overflow classification.
The operational impact of this vulnerability extends beyond simple code execution, as it provides attackers with a means to gain unauthorized access to systems running vulnerable versions of SyncBack Freeware. Remote exploitation is possible through user-assisted attack scenarios where victims must open or process the malicious profile files, making this a particularly concerning vulnerability for organizations that rely on file synchronization tools. Attackers could potentially deliver malicious payloads through compromised profile files, leading to complete system compromise, data theft, or deployment of additional malware. This vulnerability also poses risks to enterprise environments where synchronization tools are widely deployed, as it could serve as an initial compromise vector for broader network infiltration.
Mitigation strategies for CVE-2010-1688 should prioritize immediate software updates to version 3.2.21 or later, which contain the necessary patches to address the buffer overflow condition. Organizations should also implement strict file validation controls and restrict the ability to open or process profile files from untrusted sources. Network segmentation and access controls can help limit the potential impact of successful exploitation attempts. The vulnerability demonstrates the importance of proper input validation and memory safety practices, aligning with ATT&CK technique T1059 for command and scripting interpreter usage and T1068 for exploit for privilege escalation. System administrators should also consider implementing monitoring solutions to detect unusual file processing activities that might indicate exploitation attempts. Regular security assessments and vulnerability scanning should include checks for outdated synchronization software to prevent similar issues from remaining unpatched in organizational environments.
