CVSS:3.1/AC:L/AV:N/A:N/C:H/I:L/PR:L/S:C/UI:N

Attack Complexity: Low
Attack Vector: Network
Availability: None
Confidentiality: High
Integrity: Low
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: 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 on 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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Organizations should immediately implement strict input validation and output encoding on all user-supplied data in the affected parameters (hname, hemail, hpassword, hphone, hcity) within updateprofile.php and hprofile.php. Employ context-aware encoding (e.g., HTML entity encoding) to neutralize injected scripts. Deploy a Web Application Firewall (WAF) configured to detect and block XSS payloads targeting these endpoints. Conduct thorough code reviews and security testing to identify and remediate similar vulnerabilities in other components. Restrict access to the affected pages to trusted users and monitor logs for suspicious activity indicative of attempted XSS exploitation. Educate users about phishing risks stemming from XSS attacks. Plan for an urgent update or replacement of the BBMS software with a secure version once available. Ensure compliance with GDPR by promptly reporting any data breaches resulting from exploitation.

Description

A cross-site scripting (XSS) vulnerability exists in the Blood Bank Management System 1.0 within the updateprofile.php and hprofile.php components. The application fails to properly sanitize or encode user-supplied input before rendering it in response. An attacker can inject malicious JavaScript payloads into the hname, hemail, hpassword, hphone, hcity parameters, which are then executed in the victim's browser when the page is viewed.

Impact

For European organizations, particularly those in the healthcare sector using the Blood Bank Management System 1.0, this vulnerability could lead to severe confidentiality breaches involving sensitive patient and donor information. Attackers could execute malicious scripts to steal session cookies, impersonate users, or manipulate displayed data, undermining trust in healthcare services. The potential for session hijacking or data leakage could disrupt blood bank operations, delay critical medical procedures, and violate GDPR regulations, leading to legal and financial repercussions. Since the vulnerability requires only low privileges and no user interaction, it can be exploited remotely by authenticated users, increasing the risk of insider threats or compromised accounts being leveraged. The scope change in the CVSS vector suggests that exploitation could affect multiple components or users, amplifying the impact. Disruption or data compromise in blood bank systems could also have cascading effects on hospital supply chains and emergency response capabilities across Europe.

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.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
