Threat metrics

Exploit Maturity: POC

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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: 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 Vulnerable System 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 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

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

Immediate mitigation should focus on input validation and parameterized queries within the /viewbill.php script to prevent SQL injection. Organizations should audit their SourceCodester Water Billing System installations to identify affected versions and isolate vulnerable endpoints. If patching is not yet available, applying Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ID' parameter can reduce risk. Network segmentation and strict access controls around billing systems can limit exposure. Regular database backups and monitoring for anomalous queries or access patterns are recommended. Organizations should also engage with the vendor or community for updates and patches and plan for timely application once available. Finally, conducting security awareness training for administrators to recognize exploitation signs can aid early detection.

Description

A security flaw has been discovered in SourceCodester Water Billing System 1.0. This impacts an unknown function of the file /viewbill.php. The manipulation of the argument ID results in sql injection. The attack may be launched remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations, especially municipal water utilities or service providers using SourceCodester Water Billing System 1.0, this vulnerability poses a tangible risk. Successful exploitation could expose sensitive customer billing information, including personal data and payment details, leading to privacy violations under GDPR. Data integrity could also be compromised, potentially causing billing inaccuracies or service disruptions. While the vulnerability does not require authentication, the impact is somewhat limited by the specific product usage scope. However, given the critical nature of water billing systems in public infrastructure, any disruption or data breach could undermine public trust and regulatory compliance. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within an organization's IT environment.

Summary

CVE-2025-9704 is a SQL Injection vulnerability identified in SourceCodester Water Billing System version 1.0. The flaw exists in the /viewbill.php file, specifically in the handling of the 'ID' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the system then executes without proper sanitization or parameterization. This vulnerability allows remote attackers to execute arbitrary SQL commands on the backend database without requiring authentication or user interaction. The CVSS 4.0 score is 6.9 (medium severity), reflecting the ease of exploitation (network accessible, no privileges or user interaction needed) but limited impact on confidentiality, integrity, and availability (all rated low). The vulnerability could lead to unauthorized data disclosure, data modification, or partial disruption of service, depending on the database and application context. No patches or fixes have been publicly released yet, and no known exploits are currently observed in the wild, although a proof-of-concept exploit has been made public, increasing the risk of exploitation.
