Availability: None

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: 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 15 Aug 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.

What to do

Upgrade HCL Software BigFix SaaS Remediate to 8.1.14.

AI-suggested

Organizations should prioritize upgrading HCL BigFix SaaS Remediate to version 8.1.14 or later, where this vulnerability is addressed. In the absence of an immediate patch, administrators should review and harden error handling configurations to minimize the detail included in error messages, ensuring that sensitive version or platform information is not exposed. Implementing network-level controls such as restricting access to the authentication service to trusted IP ranges can reduce exposure. Monitoring logs for unusual access patterns or repeated error generation attempts can help detect reconnaissance activities. Additionally, integrating BigFix usage with a broader security information and event management (SIEM) system can provide early warning of potential exploitation attempts. Regular vulnerability assessments and penetration testing should include checks for information disclosure via error messages.

Description

HCL BigFix SaaS Authentication Service is affected by a sensitive information disclosure. Under certain conditions, error messages disclose sensitive version information about the underlying platform.

Impact

For European organizations using HCL BigFix SaaS Remediate, this vulnerability poses a moderate risk primarily through information leakage. The exposure of detailed version information can help threat actors better understand the environment and identify potential weaknesses or unpatched components. This can increase the likelihood of targeted attacks, especially in sectors where BigFix is used for endpoint management and remediation, such as finance, healthcare, and critical infrastructure. Although the vulnerability does not directly compromise system integrity or availability, the enhanced reconnaissance capability can lead to more sophisticated attacks that might exploit other vulnerabilities. Organizations with strict data protection regulations, such as GDPR, should consider the implications of any sensitive information leakage, even if indirect, as it may contribute to compliance risks. The lack of known exploits reduces immediate risk but does not eliminate the need for timely mitigation.

CWE-209Generation of Error Message Containing Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A10:2025: Mishandling of Exceptional Conditions (opens in a new tab)
The product generates an error message that includes sensitive information about its environment, users, or associated data.
Implementation
Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended).
Implementation
Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
Implementation · Attack Surface Reduction
Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
