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: 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: 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: 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.

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 26 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.
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

European organizations should prioritize upgrading Tongda OA 2017 installations to version 11.10 or later to remediate this vulnerability. Until the upgrade is applied, organizations should implement strict input validation and sanitization on the PROJ_ID_STR parameter at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads. Employing database activity monitoring can help detect anomalous queries indicative of exploitation attempts. Restricting database user privileges associated with the OA application to the minimum necessary can limit the impact of a successful injection. Network segmentation should isolate the OA system from sensitive backend systems to reduce lateral movement risk. Regularly auditing and monitoring logs for unusual access patterns or errors related to the affected endpoint (general/wiki/cp/ct/delete.php) is recommended. Finally, organizations should ensure timely application of security patches and maintain an incident response plan tailored to web application attacks.

Description

A vulnerability classified as critical has been found in Tongda OA 2017 up to 11.9. This affects an unknown part of the file general/wiki/cp/ct/delete.php. The manipulation of the argument PROJ_ID_STR leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 11.10 is able to address this issue. It is recommended to upgrade the affected component. The identifier VDB-246105 was assigned to this vulnerability.

Impact

For European organizations using Tongda OA 2017, this vulnerability poses a significant risk to sensitive business data managed within the OA platform. Successful exploitation could lead to data breaches involving confidential project information, unauthorized data manipulation, or service disruption. Given that Tongda OA is an office automation system commonly used for internal collaboration and document management, compromise could facilitate lateral movement within corporate networks, potentially exposing other critical systems. The medium severity rating suggests moderate impact, but the critical nature of SQL injection vulnerabilities and the public disclosure increase urgency. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, face heightened compliance risks and potential legal consequences if exploited. Additionally, the remote attack vector means attackers can exploit the vulnerability without physical access, increasing the threat surface.

Summary

CVE-2023-6276 is a critical SQL Injection vulnerability identified in Tongda OA 2017 versions up to 11.9, specifically affecting the file general/wiki/cp/ct/delete.php. The vulnerability arises from improper sanitization of the PROJ_ID_STR parameter, which can be manipulated by an attacker to inject malicious SQL commands. This flaw allows remote attackers to execute arbitrary SQL queries on the backend database without requiring user interaction, but does require some level of privileges (PR:L) as indicated by the CVSS vector. Exploitation could lead to unauthorized data disclosure, modification, or deletion, impacting confidentiality, integrity, and availability of the system. Although no known exploits are currently reported in the wild, the vulnerability has been publicly disclosed, increasing the risk of exploitation. The issue is resolved by upgrading to Tongda OA 2017 version 11.10 or later. The CVSS v3.1 base score is 6.3 (medium severity), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial impact on confidentiality, integrity, and availability.

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.
