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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Mar 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 2026-10-25.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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.

2) Review and tighten access controls and policies within RDM, especially the "Allow password in variable policy," ensuring it is correctly configured and monitored. 3) Implement strict credential hygiene, including multi-factor authentication (MFA) for all RDM users to reduce the risk of compromised accounts being used to exploit this vulnerability. 4) Conduct regular audits of RDM usage logs to detect any unauthorized attempts to access elevated passwords or suspicious variable usage. 5) Limit the number of users with access to elevated credentials and enforce the principle of least privilege. 6) Employ network segmentation and monitoring to detect lateral movement that could result from exploitation. 7) Educate users about the risks of credential misuse and ensure rapid incident response capabilities are in place to address potential breaches stemming from this vulnerability.

Description

Improper authorization in the variable component in Devolutions Remote Desktop Manager on Windows allows an authenticated user to use the ELEVATED_PASSWORD variable even though not allowed by the "Allow password in variable policy". This issue affects Remote Desktop Manager versions from 2025.1.24 through 2025.1.25, and all versions up to 2024.3.29.

Impact

For European organizations, the impact of CVE-2025-2600 can be substantial, particularly for enterprises relying heavily on Devolutions Remote Desktop Manager to manage remote access credentials and sessions. Unauthorized access to elevated passwords can lead to lateral movement within corporate networks, unauthorized access to critical systems, and potential data breaches. Confidentiality is the most affected security property, as attackers could extract sensitive credentials. This risk is heightened in sectors with stringent data protection requirements such as finance, healthcare, and government institutions across Europe. The vulnerability could also undermine compliance with GDPR if unauthorized access leads to personal data exposure. Additionally, the integrity and availability impacts, although rated low, could escalate if attackers leverage the compromised credentials to deploy further attacks or disrupt services. The requirement for authentication limits exploitation to insiders or compromised accounts, but this does not diminish the threat in environments with many users or weak credential management practices.

Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
