Attack Vector: Network
Attack Complexity: Low
Privileges Required: Low
User Interaction: None
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: 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: 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.

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 2026-10-26.

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

1. Immediately restrict access permissions to backup files within Dreamer CMS installations, ensuring only highly trusted administrative users can access them. 2. Implement network-level controls such as web application firewalls (WAFs) to detect and block unauthorized requests attempting to access backup files. 3. Conduct thorough audits of user privileges and remove unnecessary or excessive permissions, especially for low-privilege accounts. 4. Monitor web server logs for unusual download requests targeting backup file paths and investigate suspicious activity promptly. 5. If possible, move backup files outside of the web root directory or use secure storage mechanisms inaccessible via HTTP requests. 6. Follow Dreamer CMS vendor communications closely for official patches or updates addressing this vulnerability and apply them immediately upon release. 7. Educate administrators and developers on secure access control practices to prevent similar issues in the future. 8. Consider implementing multi-factor authentication (MFA) for CMS access to reduce the risk of account compromise that could lead to exploitation.

Description

An access control issue in Dreamer CMS v4.0.1 allows attackers to download backup files and leak sensitive information.

Impact

The primary impact of CVE-2024-25811 is the unauthorized disclosure of sensitive information through the download of backup files. This can lead to significant confidentiality breaches, exposing user data, system configurations, and potentially credentials stored within backups. Organizations using Dreamer CMS 4.0.1 risk data leakage that could facilitate further attacks such as privilege escalation, identity theft, or targeted phishing campaigns. While the vulnerability does not affect system integrity or availability directly, the exposure of sensitive data can undermine trust, lead to regulatory compliance violations (e.g., GDPR, HIPAA), and cause reputational damage. The requirement for limited privileges to exploit the vulnerability means that attackers may need to compromise a low-level account first, but once achieved, the impact can be substantial. The absence of known exploits in the wild provides a window for organizations to remediate before widespread exploitation occurs.

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
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.
