Confidentiality: None
Integrity: Low
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: 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: 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: None: There is no loss of confidentiality within the impacted component.
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: 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 2026-10-26.

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.

What to do

Upgrade Intercom Security Point (Windows) of MaLion to 5.3.4.

AI-suggested

To mitigate CVE-2025-59485, European organizations should: 1) Immediately upgrade Security Point (Windows) of MaLion to version 5.3.4 or later, where the incorrect default permissions issue is resolved. 2) Audit and restrict local user login permissions to minimize the number of users who can access affected systems. 3) Implement application whitelisting and DLL loading restrictions to prevent unauthorized DLLs from being loaded by the product. 4) Monitor file system changes in the specific folder identified as vulnerable to detect unauthorized file placements. 5) Employ endpoint detection and response (EDR) tools to identify suspicious privilege escalation attempts. 6) Harden Windows security policies, including restricting write permissions on critical directories and enforcing least privilege principles. 7) Conduct regular security awareness training to reduce insider threat risks. 8) If upgrading is not immediately possible, consider temporary compensating controls such as restricting access to the vulnerable folder or isolating affected systems. These measures go beyond generic patching advice by focusing on access control, monitoring, and layered defense strategies.

Description

CVE-2025-59485 is a vulnerability in Intercom, Inc. 's Security Point (Windows) component of MaLion prior to version 5.3.4. It involves incorrect default permissions that allow a logged-in user with limited privileges to place arbitrary files into a specific folder. If the attacker places a specially crafted DLL file, it can lead to arbitrary code execution with SYSTEM privileges. The vulnerability does not require user interaction but does require the attacker to have login access to the affected system. The CVSS score is 3.3, indicating a low severity primarily due to the requirement of local login and limited impact on confidentiality and availability. No known exploits are currently reported in the wild.

Impact

For European organizations, the impact of CVE-2025-59485 depends largely on the deployment context of Security Point (Windows) of MaLion. In environments where multiple users have login access to the same endpoint, such as shared workstations or terminal servers, this vulnerability could allow a low-privileged user to escalate privileges to SYSTEM, potentially leading to full system compromise. This could enable attackers to install persistent malware, manipulate security controls, or move laterally within the network. However, since the vulnerability requires local login and does not affect confidentiality or availability directly, its impact is somewhat limited in isolated or well-segmented environments. Organizations with strict access controls and endpoint management may see reduced risk. Nonetheless, in sectors with high-value targets or sensitive data—such as finance, government, or critical infrastructure—the ability to gain SYSTEM privileges could facilitate further attacks. The lack of known exploits in the wild reduces immediate risk but should not lead to complacency. The vulnerability could be leveraged in insider threat scenarios or by attackers who have already gained limited access.
