Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

To mitigate CVE-2025-11790, organizations should prioritize upgrading the Acronis Cyber Protect Cloud Agent to build 41124 or later, where the credential deletion issue is resolved. If you cannot patch yet, implement strict access controls to limit local high-privilege access to trusted administrators only, reducing the risk of credential exposure. Regularly audit and monitor systems for unauthorized access attempts and credential misuse. Employ endpoint detection and response (EDR) solutions to detect suspicious activities related to credential access or privilege escalation. Additionally, enforce strong credential management policies, including the use of unique, short-lived credentials and multi-factor authentication where supported. Consider isolating backup agents in segmented network zones to minimize lateral movement opportunities. Finally, maintain comprehensive logging of plan revocations and credential storage events to facilitate incident response and forensic analysis if needed.

Description

Credentials are not deleted from Acronis Agent after plan revocation. The following products are affected: Acronis Cyber Protect Cloud Agent (Linux, macOS, Windows) before build 41124.

Impact

The primary impact of CVE-2025-11790 is the potential compromise of sensitive credentials stored by the Acronis Cyber Protect Cloud Agent after plan revocation. This can lead to unauthorized access to backup or protection services, exposing confidential data and potentially allowing lateral movement within an organization's network. Although exploitation requires high privilege local access, the vulnerability increases the risk surface by retaining credentials that should have been securely removed. This can facilitate insider threats or post-compromise persistence by attackers. Organizations relying on Acronis Cyber Protect Cloud Agent for critical backup and cybersecurity functions may face data confidentiality breaches, undermining trust in their data protection strategies. The vulnerability does not directly impact system integrity or availability, but the exposure of credentials could indirectly lead to further attacks or data exfiltration. Given the cross-platform nature of the agent, the threat spans diverse IT environments, including enterprise servers, workstations, and cloud instances. The absence of known exploits reduces immediate risk but does not eliminate the potential for future targeted attacks, especially in sectors with high-value data or regulatory compliance requirements.

CWE-732Incorrect Permission Assignment for Critical Resource (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
Implementation
When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly.
Architecture and Design · Operation · Sandbox or Jail
Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
