CVE-2026-23777: Information Exposure in Dell PowerProtect Data Domain
Platform
linux
Component
dell-powerprotect-datadomain
Fixed in
8.6.0.0 or later
CVE-2026-23777 describes an information exposure vulnerability present in Dell PowerProtect Data Domain. This flaw allows a low-privileged attacker with remote access to potentially retrieve sensitive data. The vulnerability impacts versions 7.7.1.0 through 8.5, LTS2025 versions 8.3.1.0 through 8.3.1.20, and LTS2024 versions 7.13.1.0 through 7.13.1.50. Dell recommends upgrading to version 8.6.0.0 or later to address this issue.
Impact and Attack Scenarios
Successful exploitation of CVE-2026-23777 could lead to the unauthorized disclosure of sensitive data stored within the Dell PowerProtect Data Domain system. The specific data exposed is not detailed, but given the nature of Data Domain systems, it could include backups of critical business data, configuration files, or other confidential information. An attacker gaining access to this data could use it for further attacks, such as data breaches, extortion, or identity theft. The low privilege requirement for exploitation broadens the potential attack surface, as many users within an organization might have remote access to the system.
Exploitation Context
CVE-2026-23777 was published on April 17, 2026. Its severity is rated as MEDIUM. Currently, there are no publicly available proof-of-concept exploits. The EPSS score is pending evaluation. Monitor security advisories and threat intelligence feeds for any indications of active exploitation campaigns targeting this vulnerability.

Mitigation and Workarounds
The primary mitigation for CVE-2026-23777 is to upgrade Dell PowerProtect Data Domain to version 8.6.0.0 or later. Before upgrading, review Dell's compatibility matrix to ensure the new version is compatible with your existing infrastructure and applications. If an immediate upgrade is not feasible, consider implementing network segmentation to restrict remote access to the Data Domain system. Review and strengthen access controls to limit the number of users with remote access privileges. While a WAF or proxy cannot directly mitigate this vulnerability, they can help detect and block suspicious activity related to potential exploitation attempts.
