Scope: Unchanged
Confidentiality: High
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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 3 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
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 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.

AI-suggested

1. Immediate mitigation should focus on restricting network access to the Super Newsletter module endpoints, using firewalls or web application firewalls (WAFs) to limit exposure to trusted IPs only. 2. Monitor web server and application logs for unusual access patterns or attempts to access newsletter-related resources. 3. Apply any available patches or updates from Webbax or PrestaShop as soon as they are released. 4. If patches are not yet available, consider disabling or uninstalling the Super Newsletter module temporarily to prevent exploitation. 5. Conduct a thorough audit of exposed data to assess potential leakage and notify affected parties as required by law. 6. Implement strict access controls and ensure modules are configured following the principle of least privilege. 7. Educate staff about the vulnerability and encourage vigilance for phishing attempts that may leverage leaked data. 8. Plan for regular vulnerability assessments and timely updates of all third-party modules to reduce future risks.

Description

An issue was discovered in Webbax "Super Newsletter" (supernewsletter) module for PrestaShop versions 1.4.21 and before, allows local attackers to escalate privileges and obtain sensitive information.

Impact

The primary impact of CVE-2024-25839 is unauthorized disclosure of sensitive information, which can include customer data, email lists, or internal system details managed by the Super Newsletter module. This exposure can lead to privacy violations, regulatory non-compliance (e.g., GDPR), reputational damage, and potential follow-on attacks such as phishing or social engineering targeting exposed contacts. Since the vulnerability does not affect integrity or availability, direct system disruption or data manipulation is not expected. However, the confidentiality breach alone can have severe consequences for organizations, especially those handling large volumes of personal data. The ease of exploitation (no authentication or user interaction required) increases the risk of widespread attacks, particularly against e-commerce sites that have not updated or secured this module. Organizations worldwide using PrestaShop with this module are at risk, with potential financial and legal repercussions from data breaches.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
