Attack Complexity: Low
Attack Vector: Network
Availability: None
Confidentiality: High
Integrity: High
Privileges Required: Low
Scope: Changed
User Interaction: None

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

Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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).
Availability: None: There is no impact to availability within the impacted component.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted 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.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.

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.

What to do

AI-suggested

To mitigate this vulnerability, organizations should immediately implement strict input validation and sanitization on all user-supplied data, especially in the abs.php component's search functionality. Employ parameterized queries or prepared statements to prevent SQL injection attacks. Conduct a comprehensive code review of the Blood Bank Management System to identify and remediate similar vulnerabilities. Restrict database user permissions to the minimum necessary to limit the impact of potential exploits. Implement multi-factor authentication and monitor access logs for suspicious activity to detect unauthorized access attempts. Regularly update and patch the system once vendor fixes become available. Additionally, conduct penetration testing and vulnerability scanning focused on SQL injection vectors. Educate developers and administrators about secure coding practices and the importance of input validation. Finally, ensure incident response plans are in place to quickly address any exploitation attempts.

Description

CVE-2025-63535 is a critical SQL injection vulnerability in the Blood Bank Management System 1.0, specifically within the abs.php component. The application fails to properly sanitize user input in SQL queries, allowing attackers to inject arbitrary SQL code. Exploitation enables bypassing authentication and gaining unauthorized access without user interaction. The vulnerability has a CVSS score of 9.6, indicating high impact on confidentiality, integrity, and availability. No known exploits are currently in the wild, but the risk remains significant due to the critical nature of the system involved. European healthcare organizations using this system are at risk of data breaches and operational disruption. Mitigation requires immediate input validation, parameterized queries, and strict access controls.

Impact

For European organizations, especially healthcare providers and blood banks, this vulnerability could lead to unauthorized access to sensitive personal and medical data, including donor and recipient information. The ability to bypass authentication means attackers could manipulate or exfiltrate data, disrupt blood bank operations, or alter records, potentially endangering patient safety. The breach of confidentiality could violate GDPR regulations, leading to legal and financial penalties. Integrity loss could result in incorrect blood matching or inventory errors, impacting healthcare delivery. Availability impacts could arise if attackers disrupt system functionality or cause denial of service. Given the critical nature of blood bank systems in healthcare infrastructure, exploitation could have severe operational and reputational consequences across European healthcare networks.

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.
