CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N

Attack Vector: Network
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: 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.

CVE published 10 Jan 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 2026-10-26.

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.

AI-suggested

1. Immediate mitigation should include restricting external access to the /install/install.php script through network controls such as firewalls or web application firewalls (WAFs), limiting exposure to trusted internal networks only. 2. Organizations should audit their DSO2O installations to confirm the version in use and identify if the vulnerable versions 4.0 or 4.1 are deployed. 3. Until an official patch is released, consider disabling or removing the installation script if it is not required for ongoing operations. 4. Implement strict access control policies around installation and configuration files, ensuring only authorized personnel can access these resources. 5. Monitor logs and network traffic for unusual access attempts to the installation script or related endpoints. 6. Engage with the vendor for timely updates and apply patches as soon as they become available. 7. Conduct a security review of the application’s deployment architecture to ensure proper segmentation and minimize exposure of critical components. 8. Educate IT and security teams about this vulnerability to raise awareness and readiness to respond to any exploitation attempts.

Description

A vulnerability was found in DeShang DSO2O up to 4.1.0. It has been classified as critical. This affects an unknown part of the file /install/install.php. The manipulation leads to improper access controls. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-250125 was assigned to this vulnerability.

Impact

For European organizations using DeShang DSO2O versions 4.0 or 4.1, this vulnerability presents a risk of unauthorized access to installation or configuration components of the software. While the confidentiality impact is rated low, improper access control in installation scripts can sometimes be leveraged as a foothold for attackers to gather sensitive information or prepare for more severe attacks. This is particularly concerning for organizations that rely on DSO2O for critical business operations or handle sensitive customer data. The remote and unauthenticated nature of the vulnerability increases the attack surface, especially for internet-facing deployments. European organizations with less mature network segmentation or insufficient monitoring may be more vulnerable to exploitation attempts. Although no active exploitation is currently reported, the public disclosure means threat actors could develop exploits, increasing the urgency for mitigation. The medium severity rating suggests that while immediate catastrophic impact is unlikely, the vulnerability should not be ignored, especially in regulated sectors such as finance, healthcare, or government where compliance with data protection laws (e.g., GDPR) is mandatory.

Pillar weaknessCWE Top 25 (2025): #19OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
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.
