Attack Vector: Local
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Unchanged
Confidentiality: Low
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: 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: 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 Jun 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 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 implement the following specific measures: 1) Immediately review and update the caching policies on the web servers hosting IBM Sterling B2B Integrator interfaces to ensure that sensitive pages include appropriate HTTP headers such as 'Cache-Control: no-store, no-cache, must-revalidate' and 'Pragma: no-cache' to prevent browser caching of sensitive content. 2) Restrict local access to systems used to access Sterling B2B Integrator by enforcing strict endpoint security controls, including user authentication, session timeouts, and screen locking. 3) Educate users about the risks of leaving browsers open on shared or public machines and encourage the use of private/incognito browsing modes when accessing sensitive systems. 4) Monitor and audit local access logs for unusual activity that could indicate attempts to access cached data. 5) Apply any forthcoming patches or updates from IBM promptly once available. 6) Consider deploying endpoint security solutions that can detect and prevent unauthorized access to browser cache files or sensitive data remnants. 7) If feasible, isolate Sterling B2B Integrator access to dedicated, hardened workstations with minimal local user privileges to reduce the attack surface.

Description

IBM Sterling B2B Integrator and IBM Sterling File Gateway 6.0.0.0 through 6.1.2.6 and 6.2.0.0 through 6.2.0.4 could allow a local user to obtain sensitive information from a user’s web browser cache due to not using a suitable caching policy.

Impact

For European organizations, the exposure of sensitive information through browser caching in IBM Sterling B2B Integrator could lead to unauthorized disclosure of confidential business data, including transaction details, partner credentials, or other sensitive integration information. Given that Sterling B2B Integrator is often used in supply chain and financial data exchanges, such leaks could undermine trust relationships and compliance with data protection regulations such as GDPR. The local nature of the attack means that the threat is primarily from insiders or attackers who have gained local access to an endpoint used to access the Sterling interface. This could include compromised employee workstations or shared terminals. While the vulnerability does not directly allow remote exploitation or system compromise, the confidentiality breach could facilitate further attacks or data exfiltration. The impact is particularly relevant for organizations with strict data privacy requirements or those handling sensitive partner data. The lack of integrity or availability impact reduces the risk of operational disruption but does not diminish the importance of protecting sensitive information.
