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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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.

Detectable: no evidence on record.

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 immediately verify whether they are running IBM Concert Software versions 1.0.0 or 1.0.1 and assess their exposure. Since no official patches are currently linked, organizations should enforce HTTPS usage by manually enabling HTTP Strict Transport Security (HSTS) headers on their web servers or reverse proxies hosting the software. This can be done by configuring the web server to include the 'Strict-Transport-Security' header with appropriate parameters (e.g., max-age, includeSubDomains). Additionally, organizations should ensure that all network communications to the software are conducted over secure VPNs or trusted networks to reduce the risk of MITM attacks. Network monitoring should be enhanced to detect unusual traffic patterns indicative of interception attempts. Where possible, upgrading to a later, patched version of the software once available is recommended. User education on avoiding unsecured Wi-Fi networks and the use of endpoint security solutions can further reduce risk. Finally, organizations should review their incident response plans to quickly address any potential data exposure incidents related to this vulnerability.

Description

IBM Concert Software 1.0.0 and 1.0.1 could allow a remote attacker to obtain sensitive information, caused by the failure to properly enable HTTP Strict Transport Security. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques.

Impact

For European organizations using IBM Concert Software versions 1.0.0 or 1.0.1, this vulnerability poses a significant risk to the confidentiality of sensitive information transmitted between clients and servers. Given the nature of the software, which may be used in collaborative or enterprise environments, intercepted data could include proprietary business information, user credentials, or session tokens, potentially leading to unauthorized access or data breaches. The impact is particularly critical in sectors with stringent data protection requirements such as finance, healthcare, and government institutions within Europe, where GDPR mandates strict controls over personal data confidentiality. While the vulnerability does not affect data integrity or availability, the exposure of sensitive information can lead to reputational damage, regulatory penalties, and downstream attacks. The requirement for network-level interception limits the attack surface to scenarios where attackers have access to the communication channel, such as unsecured networks or compromised infrastructure, but given the increasing use of remote work and mobile access, this risk is non-negligible.

CWE-319Cleartext Transmission of Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
