Integrity: None
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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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 31 Mar 2024
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

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 2026-10-25.

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 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

AI-suggested

Organizations should first verify if they are running affected versions (4.2.0, 4.3.0, or 0) of the forum software and prioritize upgrading to patched versions once available from the vendor. In the absence of an immediate patch, administrators should review and tighten role-based access controls, ensuring that non-editing teachers cannot perform forum exports or access data beyond their group. Disabling the forum export feature for non-administrative roles or restricting it to trusted users can reduce exposure. Monitoring and auditing export activities can help detect unauthorized data exports. Additionally, consider implementing network segmentation and multi-factor authentication to limit access to the forum system. Communicating with users about the sensitivity of group data and enforcing strict data handling policies will further mitigate risks. Finally, stay updated with vendor advisories for official patches or workarounds.

Description

Separate Groups mode restrictions were not honored when performing a forum export, which would export forum data for all groups. By default this only provided additional access to non-editing teachers.

Impact

The primary impact of CVE-2024-25981 is unauthorized disclosure of forum data across group boundaries. For educational institutions or organizations using this forum software to segment discussions by groups, this could lead to leakage of sensitive information such as student discussions, internal communications, or confidential topics. Although the exposure is limited to read-only access by non-editing teachers, it undermines the confidentiality guarantees of group separation. This could damage trust, violate privacy policies, or lead to compliance issues, especially in regulated environments handling personal or sensitive data. The vulnerability does not affect data integrity or availability, so operational disruption or data manipulation risks are minimal. Since exploitation requires at least low-level privileges (non-editing teacher role), the risk is limited to insiders or users with some authenticated access, reducing the likelihood of external attackers exploiting this flaw directly.
