Attack Vector: Network
Attack Complexity: Low

Scope: Unchanged
Confidentiality: None
Integrity: Low
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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. Immediate mitigation should include restricting access to the /DataBackup.php endpoint via web application firewalls (WAFs) or network-level controls to limit exposure. 2. Implement input validation and parameterized queries or prepared statements in the FoxCMS codebase to prevent SQL Injection. 3. Monitor web server and application logs for suspicious requests targeting the 'id' parameter in /DataBackup.php. 4. If possible, disable or remove the /DataBackup.php functionality temporarily until a patch is available. 5. Conduct a thorough audit of database integrity and backups to detect any unauthorized changes. 6. Engage with FoxCMS developers or community to obtain or request an official patch or update addressing this vulnerability. 7. Educate administrators and developers about secure coding practices to prevent similar vulnerabilities. 8. Consider deploying runtime application self-protection (RASP) tools to detect and block injection attempts dynamically.

Description

SQL Injection vulnerability in FoxCMS v1.2.6 and before allows a remote attacker to execute arbitrary code via the.file /DataBackup.php and the operation on the parameter id.

Impact

For European organizations using FoxCMS, this vulnerability poses a moderate risk primarily to data integrity. Attackers exploiting the SQL Injection can modify or corrupt database records, potentially affecting website content, user data, or configuration settings. This could lead to misinformation, loss of trust, or operational disruptions if the CMS is used for critical content management. While confidentiality and availability impacts are not directly indicated, the integrity compromise can have cascading effects, such as enabling further attacks or causing business process failures. Organizations in sectors with strict data integrity requirements, such as government, finance, or healthcare, may face regulatory and reputational consequences if exploited. The remote and unauthenticated nature of the exploit increases the likelihood of automated scanning and attacks, especially if FoxCMS is publicly accessible. Given the absence of known exploits, the immediate risk is moderate, but the potential for future exploitation remains if patches are not applied promptly.

CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #2OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
