Speak to Experts

CVE-2025-64648 is a medium severity vulnerability affecting IBM Concert versions 1.0.0 through 2.2.0. This vulnerability allows the transmission of sensitive data in clear text, which could enable attackers to exploit this weakness using man-in-the-middle techniques. The potential risk to organizations is significant due to the high confidentiality impact associated with this vulnerability.

With a CVSS score of 5.9, this vulnerability represents a medium level of risk. Organizations should prioritize addressing this vulnerability as it can expose sensitive information during data transmission. Immediate remediation is crucial to mitigate potential data breaches.

The exploitation status indicates that there are currently no known exploits or publicly available proof of concepts for this vulnerability, but the clear text transmission poses a significant risk. Organizations should take proactive measures to secure their data transmissions and ensure that sensitive information is encrypted.

Organizations should prioritize patching immediately. By doing so, they can prevent unauthorized access and the potential compromise of sensitive data.

Vulnerability Details

The official description for CVE-2025-64648 states that IBM Concert versions 1.0.0 through 2.2.0 transmit data in clear text, which allows an attacker to obtain sensitive information using man-in-the-middle techniques. This vulnerability is classified under CWE-319, indicating that it relates to the use of improper encryption or clear text transmission.

The CVSS score for this vulnerability is 5.9, categorized as medium severity. The attack vector is network-based, with a high attack complexity. No privileges are required, and no user interaction is necessary, making it easier for attackers to exploit this vulnerability.

The confidentiality impact is high, while the integrity and availability impacts are none. This means that sensitive information could be exposed, but the attack does not affect the integrity or availability of the system.

Technical Analysis

The root cause of this vulnerability lies in the failure to encrypt sensitive data during transmission. This oversight allows attackers to intercept and read the data without any encryption safeguards.

The attack vector is categorized as network-based, indicating that an attacker can exploit this vulnerability remotely over a network connection. The attack complexity is high, requiring certain conditions to be met for successful exploitation, such as being able to intercept the data stream.

No privileges are required for exploitation, and user interaction is not necessary. This means that an attacker can exploit this vulnerability without needing access to the system or requiring any action from users.

The impact on confidentiality is high, as sensitive data can be exposed to attackers. However, the integrity and availability of the system remain unaffected.

Risk & Impact Analysis

The risk to organizations includes potential exposure of sensitive information, which could lead to data breaches and loss of customer trust. The blast radius of this vulnerability can extend to all users of the affected versions of IBM Concert.

Organizations should assess their deployment risk and evaluate their exposure to this vulnerability. Given the medium severity and high confidentiality impact, it is crucial for organizations to address this vulnerability swiftly.

The urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle.
