Dell AppSync 4.6.0 Incorrect Permission Assignment Vulnerability

Dell AppSync version 4.6.0 is vulnerable to an incorrect permission assignment issue. A local attacker with low privileges can exploit this vulnerability to escalate their privileges on the affected system. This vulnerability, identified as CVE-2026-22768, could allow an attacker to gain unauthorized access to sensitive data or execute arbitrary code with elevated privileges. Successful exploitation requires local access and user interaction (UI:R). This vulnerability poses a significant risk to organizations using the affected version of Dell AppSync, as it could lead to data breaches, system compromise, and other security incidents. Defenders should prioritize patching or mitigating this vulnerability to prevent potential exploitation.

Attack Chain

1. The attacker gains initial local access to a system running Dell AppSync 4.6.0.
2. The attacker identifies the critical resource with incorrect permission assignments (CWE-732).
3. The attacker crafts a malicious input or action that triggers the vulnerable code path within AppSync. This requires some user interaction, such as clicking a link or opening a file.
4. Due to the incorrect permission assignments, the attacker is able to modify or access the critical resource.
5. The attacker leverages the modified resource to execute arbitrary code or gain access to sensitive data.
6. The attacker escalates privileges by exploiting the vulnerability.
7. The attacker uses their elevated privileges to install malware, exfiltrate data, or perform other malicious activities.

Impact

Successful exploitation of this vulnerability allows a low-privileged local attacker to elevate their privileges to that of a system administrator. While the specific number of affected organizations is unknown, any organization using Dell AppSync 4.6.0 is potentially vulnerable. A successful attack could result in unauthorized access to sensitive data, system compromise, and potential data breaches. The CVSS v3.1 base score for this vulnerability is 7.3 (HIGH), reflecting the significant risk it poses.

Recommendation

• Apply the security update provided by Dell as detailed in DSA-2026-163 to patch CVE-2026-22768.
• Monitor systems running Dell AppSync for suspicious activity indicative of privilege escalation attempts.
• Review and harden permission assignments on critical resources within the Dell AppSync environment to prevent future vulnerabilities of this type (CWE-732).
