CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: None
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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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.

AI-suggested

To mitigate this vulnerability, European organizations should first inventory all instances of IBM Concert Software versions 1.0.0 through 1.1.0 in their environment. Until an official patch is released, organizations should implement strict access controls to limit local access to systems running the affected software, including network segmentation and least privilege principles. Monitoring and logging of access to these systems should be enhanced to detect suspicious activities. If possible, replace or upgrade to versions of IBM Concert Software that do not contain hard-coded credentials or apply vendor-provided workarounds. Additionally, organizations can perform binary analysis or reverse engineering to identify and remove or replace hard-coded credentials with secure, dynamically managed secrets using enterprise key management solutions. Employing application-layer encryption with keys managed outside the software can reduce reliance on embedded secrets. Regularly audit and rotate any credentials associated with the software. Finally, educate internal teams about the risks of hard-coded credentials and enforce secure coding practices for in-house developed integrations or customizations.

Description

IBM Concert Software 1.0.0 through 1.1.0 contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.

Impact

For European organizations using IBM Concert Software, this vulnerability poses a significant risk to confidentiality. Attackers who gain local access—such as through compromised internal systems or insider threats—can extract hard-coded credentials to access sensitive communications or data. This could lead to unauthorized disclosure of intellectual property, customer data, or internal communications. Since the vulnerability does not affect integrity or availability, the primary concern is data confidentiality. However, the breach of confidentiality can indirectly impact compliance with GDPR and other data protection regulations, exposing organizations to legal and financial penalties. The medium severity score reflects that exploitation requires local access, limiting remote attack vectors but still posing a risk in environments with shared or insufficiently segmented access. European enterprises with critical infrastructure or sensitive data processed via IBM Concert Software are particularly at risk. The lack of patches increases exposure duration, and the absence of known exploits does not preclude targeted attacks by skilled adversaries. Overall, the vulnerability could facilitate espionage, data theft, or lateral movement within networks, especially in sectors like finance, manufacturing, or government where IBM products are commonly deployed.

CWE-798Use of Hard-coded Credentials (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product contains hard-coded credentials, such as a password or cryptographic key.
Architecture and Design
For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320).
Architecture and Design
For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a "first login" mode that requires the user to enter a unique strong password or key.
Architecture and Design
If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
