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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 27 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 29 Oct 2026.

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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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

Upgrade Centreon Web on Central Server to 25.10.8; centreon/centreon-web to 25.10.8, 24.10.20 or 24.04.24.

AI-suggested

To mitigate CVE-2026-2751, organizations should immediately restrict access to Centreon Web Central Server interfaces to trusted administrators and networks, minimizing exposure. Implement strict input validation and sanitization on all user-supplied data, especially array keys in Service Dependencies modules, to prevent injection attacks. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting Centreon endpoints. Monitor logs for unusual database query patterns or failed deletion attempts that may indicate exploitation attempts. Segregate Centreon database access with least privilege principles, ensuring that the web application account has minimal rights to reduce potential damage. Stay alert for official patches or updates from Centreon and apply them promptly once released. Additionally, conduct regular security assessments and penetration tests focusing on web application vulnerabilities to detect similar issues proactively.

Description

Blind SQL Injection via unsanitized array keys in Service Dependencies deletion. Vulnerability in Centreon Centreon Web on Central Server on Linux (Service Dependencies modules) allows Blind SQL Injection.This issue affects Centreon Web on Central Server before 25.10.8, 24.10.20, 24.04.24.

Impact

The impact of CVE-2026-2751 is substantial for organizations relying on Centreon Web for IT infrastructure monitoring and management. Successful exploitation can lead to unauthorized disclosure of sensitive monitoring data, including system statuses, network configurations, and potentially credentials stored within the database. Integrity of the monitoring data can be compromised, allowing attackers to alter service dependencies and potentially mask malicious activities or cause false alerts. Although availability impact is limited, the loss of data integrity and confidentiality can severely disrupt incident response and operational awareness. This can lead to prolonged undetected breaches, compliance violations, and damage to organizational reputation. Given Centreon's deployment in critical infrastructure sectors such as telecommunications, finance, and government, the vulnerability poses a risk of targeted attacks aiming to undermine operational stability and security monitoring capabilities.

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.
