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: 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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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-2025-64065 effectively, organizations should implement the following specific measures: 1) Immediately restrict access to the /api/V2/pp_udfv_admin endpoint using network-level controls such as IP whitelisting or VPNs to limit exposure. 2) Enforce strict server-side authorization checks ensuring that only users with verified administrative privileges can invoke the LoginAs functionality. This includes validating the caller's role before processing impersonation requests. 3) Require multi-factor authentication (MFA) for all administrative accounts to reduce the risk of compromised credentials being leveraged. 4) Implement logging and real-time monitoring of PATCH requests to the vulnerable endpoint, with alerts for anomalous impersonation attempts or unusual user switching activities. 5) Conduct thorough audits of user sessions and privilege escalations to detect potential abuse. 6) If possible, disable or remove the LoginAs feature temporarily until a secure patch or update is available from the vendor. 7) Engage with Primakon to obtain security patches or updates addressing this vulnerability and apply them promptly once released. 8) Educate users and administrators about the risks of privilege escalation and the importance of safeguarding credentials. These targeted actions go beyond generic advice by focusing on access control hardening, monitoring, and vendor coordination specific to this vulnerability.

Description

The Primakon Pi Portal 1.0.18 API /api/V2/pp_udfv_admin endpoint, fails to perform necessary server-side validation. The administrative LoginAs or user impersonation feature is vulnerable to a access control failure. This flaw allows any authenticated low-privileged user to execute a direct PATCH request, enabling them to impersonate any other arbitrary user, including application Administrators. This is due to a Broken Function Level Authorization failure (the function doesn't check the caller's privilege) compounded by an Insecure Design that permits a session switch without requiring the target user's password or an administrative token and only needs email of user.

Impact

For European organizations, the impact of CVE-2025-64065 is substantial. Exploitation allows attackers to impersonate any user, including administrators, resulting in complete loss of confidentiality, integrity, and availability of the affected system. This can lead to unauthorized data access, modification, or deletion, disruption of business operations, and potential lateral movement within networks. Organizations handling sensitive personal data, financial information, or critical infrastructure are at heightened risk of regulatory penalties under GDPR and other data protection laws if breaches occur. The vulnerability's ease of exploitation means that even low-privileged insiders or compromised user accounts can escalate privileges rapidly, increasing insider threat risks. Additionally, the ability to impersonate administrators can facilitate further attacks, such as deploying malware, altering configurations, or exfiltrating data. The lack of user interaction and remote exploitability further exacerbate the threat, making timely detection and response challenging. Overall, this vulnerability could severely undermine trust in affected applications and cause significant operational and reputational damage across European sectors.

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.
