OS command injection in Dell PowerProtect Data Domain across four supported release tracks allows a high-privileged local attacker to execute arbitrary operating system commands. Affected versions span the main release line (7.7.1.0-8.7) as well as LTS2024, LTS2025, and LTS2026 branch releases. No public exploit code or active exploitation has been identified at time of analysis; the local access and high-privilege prerequisites substantially constrain the realistic attack surface despite the full C/I/A impact scores.
Arbitrary OS command execution in Dell PowerProtect Data Domain (versions 7.7.1.0 through 8.7, plus the LTS2026, LTS2025 and LTS2024 branches) lets a high-privileged, remotely-authenticated attacker run operating-system commands on the backup appliance by injecting special characters into an OS command context. The flaw was reported by Dell and is addressed in advisory DSA-2026-278; no public exploit identified at time of analysis and it is not listed in CISA KEV. Because it grants full command execution on a data-protection appliance, successful exploitation can compromise the confidentiality, integrity and availability of backup data.
OS command injection in Dell PowerProtect Data Domain (versions 7.7.1.0 through 8.7, plus the LTS2026, LTS2025, and LTS2024 maintenance branches) lets an authenticated high-privileged remote attacker execute arbitrary operating-system commands on the appliance via improperly neutralized special characters (CWE-78). Because the attacker already holds elevated privileges, the flaw functions as a privilege-boundary and integrity break - turning administrative access into full underlying-OS command execution with high confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; it was reported by Dell and fixed in advisory DSA-2026-278.
Authenticated OS command injection in Dell PowerProtect Data Domain (versions 7.7.1.0 through 8.7, plus LTS2026 8.6.1.0-8.6.1.10, LTS2025 8.3.1.0-8.3.1.30, and LTS2024 7.13.1.0-7.13.1.70) lets a high-privileged remote attacker inject arbitrary operating-system commands and execute them on the appliance. Successful exploitation yields full confidentiality, integrity, and availability impact (CVSS 7.2), effectively giving an authenticated administrator command execution on the underlying OS of a backup/data-protection system. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Integer overflow in Dell PowerProtect Data Domain across multiple release trains (main, LTS2024, LTS2025, LTS2026) exposes backup and data protection infrastructure to remote denial of service by an unauthenticated attacker. The CVSS vector (AV:N/AC:H/PR:N) confirms network-accessible, unauthenticated exploitation, though high attack complexity constrains practical exploitation to adversaries who can satisfy specific preconditions. No public exploit has been identified at time of analysis, and the vulnerability has not been added to the CISA Known Exploited Vulnerabilities catalog.
Symlink-following vulnerability in Dell PowerProtect Data Domain allows a high-privileged remote attacker to traverse outside intended file paths and read arbitrary files, resulting in information disclosure. Multiple version branches are affected, including the current mainstream 8.7 release, LTS2026 builds through 8.6.1.10, LTS2025 builds through 8.3.1.30, and LTS2024 builds through 7.13.1.70. Dell published advisory DSA-2026-278 addressing this issue; no public exploit code or active exploitation has been identified at time of analysis.
Format string exploitation in Dell PowerProtect Data Domain enables remote high-privileged attackers to disclose memory contents and crash the service across multiple concurrent release trains. Affected versions span the mainline (7.7.1.0-8.7), LTS2026 (8.6.1.0-8.6.1.10), LTS2025 (8.3.1.0-8.3.1.30), and LTS2024 (7.13.1.0-7.13.1.70) branches, creating broad organizational exposure for enterprises running any supported Data Domain release. No public exploit or confirmed active exploitation has been identified at time of analysis; the mandatory high-privilege prerequisite substantially constrains the realistic attacker pool.
Dell PowerProtect Data Domain's handling of a less-trusted data source allows a remote, high-privileged attacker to perform limited information tampering, classified under CWE-348. Affected are multiple release trains spanning versions 7.7.1.0 through 8.7, including LTS2024, LTS2025, and LTS2026 long-term support branches. With a CVSS base score of 2.7 (Low) and no confirmed active exploitation or public proof-of-concept, real-world impact is constrained by the high privilege requirement and the limited integrity-only scope of the vulnerability.
Path traversal in Dell PowerProtect Data Domain allows a locally authenticated high-privileged attacker to read files outside restricted directories, resulting in information disclosure. Affected deployments span multiple release trains - standard releases 7.7.1.0 through 8.6, LTS2026 8.6.1.0-8.6.1.10, LTS2025 8.3.1.0-8.3.1.30, and LTS2024 7.13.1.0-7.13.1.70. No public exploit identified at time of analysis; the low CVSS score of 2.3 correctly reflects the high privilege and local access prerequisites that substantially constrain real-world exploitation scope.
Incorrect permission assignment on a critical resource in Dell PowerProtect Data Domain exposes sensitive data to high-privileged local attackers across a broad range of supported release trains. The flaw (CWE-732) means a resource - likely a file, directory, or configuration object - carries overly permissive access controls, allowing a local attacker operating with elevated privileges to read data they are not authorized to access. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, but the breadth of affected versions (seven release trains spanning 2024-2026 LTS and mainline builds) increases aggregate exposure across enterprise backup environments.
Link-following exploitation in Dell PowerProtect Data Domain enables a high-privileged local attacker to read files outside their intended access scope by manipulating symbolic or hard links before file access operations resolve. Affected across multiple release trains - mainline 7.7.1.0 through 8.6, LTS2026 8.6.1.10 and below, LTS2025 8.3.1.30 and below, and LTS2024 7.13.1.70 and below. No public exploit code or active exploitation confirmed at time of analysis; risk is bounded by the requirement for pre-existing high-privilege local access.
Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) versions prior to 8.3.0.15 contain an Insufficient Granularity of Access Control vulnerability. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
