CVE-2026-53479: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Dell PowerProtect Data Domain
Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an improper neutralization of special elements used in an OS command ('OS command Injection') vulnerability. A remote high privileged attacker could potentially exploit this vulnerability, leading to protection mechanism bypass. This is a Critical vulnerability as it allows an attacker to invoke arbitrary command execution with root privileges; so Dell recommends customers to upgrade at the earliest opportunity.
AI Analysis
Technical Summary
CVE-2026-53479 is an OS command injection vulnerability (CWE-78) in Dell PowerProtect Data Domain affecting versions 7.7.1.0 through 8.7 and certain LTS releases. It involves improper neutralization of special elements in OS commands, enabling a remote attacker with high privileges to execute arbitrary commands as root, leading to potential protection mechanism bypass. The CVSS v3.1 base score is 7.2, indicating high severity. No vendor advisory or patch information is currently available, and the vulnerability is not known to be exploited in the wild.
Potential Impact
A remote attacker with high privileges can exploit this vulnerability to execute arbitrary OS commands with root privileges on affected Dell PowerProtect Data Domain systems. This can lead to bypassing protection mechanisms and full system compromise. The impact includes confidentiality, integrity, and availability loss as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Dell recommends upgrading affected versions at the earliest opportunity once a fix is released. Until then, restrict high-privileged remote access to the affected systems to trusted personnel only.
