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

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 2026-10-26.

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

1. Apply official patches or updates from SourceCodester as soon as they become available to address the vulnerability directly. 2. In the absence of patches, implement immediate input validation and sanitization on the register_username parameter to block malicious SQL payloads. 3. Employ parameterized queries or prepared statements in the application code to prevent SQL injection. 4. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. 5. Monitor web server and database logs for unusual queries or repeated failed attempts targeting the register_username parameter. 6. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts against /register.php. 7. Conduct regular security assessments and code reviews focusing on input handling and database interactions. 8. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases.

Description

A vulnerability was detected in SourceCodester Simple E-Commerce Bookstore 1.0. The affected element is an unknown function of the file /register.php. Performing manipulation of the argument register_username results in sql injection. The attack is possible to be carried out remotely. The exploit is now public and may be used.

Impact

For European organizations using SourceCodester Simple E-Commerce Bookstore 1.0, this vulnerability poses a risk of unauthorized data access, including customer personal information and transactional data. Exploitation could lead to data breaches, damaging customer trust and resulting in regulatory penalties under GDPR. Additionally, attackers could modify or delete data, impacting the integrity and availability of e-commerce services, potentially causing financial loss and reputational damage. The remote and unauthenticated nature of the vulnerability increases the attack surface, making it easier for threat actors to exploit without insider access. Given the critical role of e-commerce in many European economies, especially in countries with large online retail sectors, the impact could be significant if exploited at scale. Furthermore, compromised systems could be leveraged for further attacks within organizational networks or used as a foothold for broader cybercrime activities.

Summary

CVE-2025-11480 is a SQL injection vulnerability identified in SourceCodester Simple E-Commerce Bookstore version 1.0. The vulnerability resides in the /register.php script, specifically in the handling of the register_username parameter. An attacker can remotely send crafted input to this parameter to manipulate SQL queries executed by the application. This manipulation can lead to unauthorized access or modification of the underlying database, potentially exposing sensitive user data or allowing further compromise of the system. The vulnerability requires no authentication or user interaction, making it accessible to any remote attacker. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no confirmed exploits are reported in the wild, the public availability of exploit code increases the risk of exploitation. The lack of vendor patches at the time of publication necessitates immediate defensive measures. This vulnerability is particularly concerning for e-commerce platforms that handle sensitive customer information and payment data, as exploitation could lead to data breaches, fraud, or service disruption.
