Availability: Low

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: 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 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: 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 21 Nov 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.

AI-suggested

1. Immediately inventory and identify all instances of IBM Concert Software versions 1.0.0 through 2.0.0 within the organization. 2. Restrict network access to IBM Concert Software interfaces to trusted internal networks and limit exposure to the internet or untrusted zones. 3. Implement strict access controls and monitor for unusual privilege escalations or suspicious user activities related to IBM Concert Software. 4. Employ application-layer firewalls or endpoint detection systems capable of identifying anomalous UI manipulation or click hijacking behaviors. 5. Educate users about the risk of unauthorized UI actions and encourage reporting of unexpected software behavior. 6. Monitor IBM security advisories closely for the release of patches or updates addressing CVE-2025-36149 and apply them promptly once available. 7. Consider deploying compensating controls such as multi-factor authentication and session monitoring to reduce the risk of exploitation by low-privilege attackers. 8. Conduct regular security assessments and penetration testing focusing on UI-layer vulnerabilities and clickjacking techniques within the IBM Concert Software environment.

Description

IBM Concert Software 1.0.0 through 2.0.0 could allow a remote attacker to hijack the clicking action of the victim.

Impact

For European organizations, this vulnerability could lead to unauthorized actions being executed remotely on systems running IBM Concert Software, potentially compromising sensitive data or disrupting business processes. The hijacking of click actions could allow attackers to perform unintended commands, leading to data integrity issues or availability problems if critical functions are manipulated. Although the impact is rated medium, organizations in sectors such as finance, government, and critical infrastructure that rely on IBM Concert Software for operational tasks may face increased risk. The requirement for low privileges means insider threats or compromised accounts could exploit this vulnerability more easily. The lack of user interaction requirement increases the risk of automated exploitation once a vulnerability is weaponized. Given the absence of patches, organizations must be vigilant to prevent exploitation and limit exposure. The impact on confidentiality, integrity, and availability, while limited, could cascade in complex environments, affecting compliance with European data protection regulations such as GDPR if sensitive data is exposed or altered.

CWE-1021Improper Restriction of Rendered UI Layers or Frames (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.
Implementation
The use of X-Frame-Options allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content.
Implementation
A developer can use a "frame-breaker" script in each page that should not be framed. This is very helpful for legacy browsers that do not support X-Frame-Options security feature previously mentioned.
Implementation
This defense-in-depth technique can be used to prevent the improper usage of frames in web applications. It prioritizes the valid sources of data to be loaded into the application through the usage of declarative policies.
