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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system 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 vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the vulnerable system.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Subsequent System.
Subsequent system 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 to the Subsequent System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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.

AI-suggested

1. Immediate mitigation should focus on restricting and monitoring administrative access to the Absolute Secure Access management console. Implement strict access controls, multi-factor authentication (MFA), and regular auditing of admin accounts and activities. 2. Network segmentation should be enforced to limit access to the management console only to trusted administrative networks and personnel. 3. Employ application-layer protections such as Web Application Firewalls (WAFs) to detect and block suspicious deserialization payloads or anomalous requests targeting the console. 4. Monitor logs and alerts for unusual behavior indicative of exploitation attempts, including unexpected configuration changes or code execution traces. 5. Engage with Absolute Security for official patches or updates addressing this vulnerability and plan for prompt deployment once available. 6. Conduct internal security awareness and training focused on safeguarding administrative credentials and recognizing potential insider threats. 7. As a longer-term measure, evaluate the security posture of the Secure Access deployment and consider alternative solutions or additional compensating controls if patching is delayed. 8. Implement runtime application self-protection (RASP) or endpoint detection and response (EDR) tools to detect and prevent exploitation attempts in real-time.

Description

CVE-2025-49083 is a vulnerability in the management console of Absolute Secure Access after version 12.00 and prior to version 13.56. Attackers with administrative access to the console can cause unsafe content to be deserialized and executed in the security context of the console. The attack complexity is low and there are no attack requirements. Privileges required are high and there is no user interaction required. The impact to confidentiality is low, impact to integrity is high and there is no impact to availability. The impact to the confidentiality and integrity of subsequent systems is low and there is no subsequent system impact to availability.

Impact

For European organizations, the impact of CVE-2025-49083 is significant primarily in environments where Absolute Secure Access is deployed for managing secure access and network security. Since the vulnerability requires administrative access to the management console, the threat is most relevant in scenarios where internal threat actors or compromised administrator accounts exist. Exploitation could lead to unauthorized modification of security policies, configurations, or access controls, undermining the integrity of the security infrastructure. This could facilitate further attacks, lateral movement, or data manipulation within the organization. Although confidentiality and availability impacts are low or none, the integrity compromise can disrupt trust in security controls and potentially expose organizations to compliance risks, especially under stringent European data protection regulations such as GDPR. The lack of required user interaction and low attack complexity increases the risk if administrative credentials are compromised. Given the critical role of Secure Access in controlling network entry points, any compromise could have cascading effects on organizational security posture. Therefore, European enterprises relying on this product should consider this vulnerability a high priority for remediation to maintain operational security and regulatory compliance.

CWE-502Deserialization of Untrusted Data (opens in a new tab)
Base weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #15OWASP Top 10 A08:2025: Software or Data Integrity Failures (opens in a new tab)
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Architecture and Design · Implementation
If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
Implementation
When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
Implementation
Explicitly define a final object() to prevent deserialization.
