Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 2026-10-25.

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 using WBiz Desk 1.2 should immediately audit their deployments for exposure of the ticket.php endpoint and the 'tk' parameter. Specific mitigations include: 1) Implementing strict input validation and sanitization on the 'tk' parameter to reject or neutralize SQL control characters; 2) Refactoring database queries to use parameterized prepared statements or stored procedures to prevent injection; 3) Restricting access to the ticket.php endpoint to trusted users or IP ranges where feasible; 4) Monitoring application logs for unusual or malformed requests targeting the 'tk' parameter; 5) Conducting penetration testing to verify the absence of injection vulnerabilities; 6) If possible, upgrading to a patched version of WBiz Desk once available or applying vendor-provided patches; 7) Employing Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this parameter; 8) Educating developers and administrators about secure coding practices to prevent similar vulnerabilities. These measures should be prioritized given the lack of current patches and the potential impact on data confidentiality.

Description

CVE-2023-53935 is a medium severity SQL injection vulnerability in Codester's WBiz Desk version 1.2. It allows non-admin users to manipulate the 'tk' parameter in ticket.php to inject malicious SQL queries using UNION-based techniques. This can lead to unauthorized extraction of sensitive database information without requiring user interaction or elevated privileges beyond low-level access. The vulnerability is remotely exploitable over the network with low attack complexity. Although no known exploits are currently reported in the wild, affected organizations should prioritize patching or mitigating this issue to prevent data breaches. European organizations using WBiz Desk 1.2 are at risk, especially those with sensitive customer or operational data stored in the application database. Mitigation involves input validation, parameterized queries, and restricting access to vulnerable endpoints.

Impact

For European organizations, exploitation of this vulnerability could result in unauthorized disclosure of sensitive business and customer data, leading to reputational damage, regulatory penalties under GDPR, and potential operational disruptions. Organizations relying on WBiz Desk 1.2 for ticketing and customer support management are particularly at risk. The exposure of internal ticketing data could reveal confidential business processes or customer issues, which may be leveraged for further attacks or competitive disadvantage. Given the medium severity and ease of exploitation, attackers could automate attacks to extract large volumes of data. This risk is heightened in sectors with strict data protection requirements such as finance, healthcare, and public administration. Furthermore, the vulnerability could be exploited as a foothold for lateral movement within networks if the compromised application has access to other internal systems. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code could be developed and shared rapidly.
