SQL Injection Attacks Affecting Singapore Websites
Published Sources: SingCERT
What is affected, what to do
Amidst global reports of ongoing website defacement campaigns, SingCERT has observed Structured Query Language (SQL) injection attacks against a few websites belonging to local organisations, which have led to unauthorised access, website defacement, and/or compromise of sensitive customer or organisational data. Organisations that maintain an online presence must remain vigilant against potential cyber-attacks on their websites.

Priority (0–325)
The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

Exploit maturity
An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.
Read in glossary- no public PoC known
KEV status
The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

Classification under NIS2 and CRA
Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.
NIS2
NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.
Read in glossary- Handle the vulnerability in regular vulnerability handling under Art. 21(2)(e) NIS2.
CRA
The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.
Read in glossary- From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.
ISO/IEC 27001
ISO/IEC 27001 is the internationally leading standard for an information security management system (ISMS). It describes a risk-based, process-oriented framework to systematically plan, implement, review and improve information security.

Description
Amidst global reports of ongoing website defacement campaigns, SingCERT has observed Structured Query Language (SQL) injection attacks against a few websites belonging to local organisations, which have led to unauthorised access, website defacement, and/or compromise of sensitive customer or organisational data. Organisations that maintain an online presence must remain vigilant against potential cyber-attacks on their websites. Measures to Secure Your Website Against SQL Injections Organisations are urged to: Install web application firewalls and security plugins to block unauthorised traffic and malicious requests from accessing your network or system. These help to safeguard against threats like SQL code injection, or brute-force attacks. Limit the privileges of the user account that is used to access the database. This action can help prevent threat actors from accessing sensitive data or executing malicious SQL code. Validate user input, such as special characters and null characters, at both the client and server ends. Keep the database software and any associated applications up to date with the latest security patches and updates. This can help prevent known vulnerabilities from being exploited by threat actors. Use stored procedures, which can help prevent SQL injection attacks by separating the SQL code from the user input. This ensures that the user input is treated as data rather than as part of the SQL code. For more preventive measures and recovery steps, please refer to our advisory on protecting your website from cyber-attacks . Singapore organisations who are affected by a cyber incident or have evidence of any suspicious compromise of your networks should report to SingCERT. A report can be made via SingCERT’s Incident Reporting Form at https://go.gov.sg/singcert-incident-reporting-form .
