Overview
A critical security vulnerability, identified as CVE-2025-57489, has been discovered in Shirt Pocket SuperDuper! version 3.10. This vulnerability allows a local attacker to escalate their privileges to root, potentially gaining full control of the affected system. The issue stems from incorrect access control within the SDAgent component, specifically involving the improper use of a setuid binary.
Technical Details
CVE-2025-57489 arises from an incorrect access control implementation within the SDAgent component of SuperDuper! v3.10. The vulnerable component uses a setuid binary that, under certain circumstances, fails to properly validate user input or permissions. This allows an attacker with limited privileges to manipulate the binary’s behavior and execute arbitrary code with root privileges. The exact mechanism of exploitation likely involves crafting malicious input that bypasses the intended security checks of the setuid binary within SDAgent.
CVSS Analysis
Currently, a CVSS score has not been assigned to CVE-2025-57489. However, given the potential for full system compromise through privilege escalation to root, it is expected that the assigned score will be critical or high. The lack of immediate information likely indicates a delay in the official analysis. Keep an eye on the NVD (National Vulnerability Database) for the official CVSS score as it becomes available.
Possible Impact
The impact of CVE-2025-57489 is severe. A successful exploit could allow an attacker to:
- Gain complete control of the compromised system.
- Install malware, including rootkits.
- Access sensitive data, including user credentials and financial information.
- Modify system configurations.
- Wipe the system.
- Use the compromised system as a launchpad for further attacks.
