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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within 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 2026-10-25.

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

1. Implement strict input validation and output encoding on the 'Question' parameter within /editQuestion.php to neutralize malicious scripts. 2. Deploy Web Application Firewalls (WAFs) with robust XSS detection and blocking capabilities to filter malicious payloads before reaching the application. 3. Conduct thorough code reviews and security testing of the Interview Management System to identify and remediate similar input handling flaws. 4. Educate HR and recruitment staff about phishing and social engineering risks related to XSS attacks to reduce user interaction exploitation. 5. Monitor web server logs and application behavior for unusual patterns indicative of XSS attempts or exploitation. 6. If possible, isolate the Interview Management System behind secure network segments and restrict access to trusted users. 7. Engage with the vendor or community to obtain or develop patches addressing this vulnerability. 8. Consider migrating to alternative, actively maintained recruitment management solutions with better security track records if patching is not feasible.

Description

A security flaw has been discovered in SourceCodester Interview Management System 1.0. Affected is an unknown function of the file /editQuestion.php. The manipulation of the argument Question results in cross site scripting. It is possible to launch the attack remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations, the impact of CVE-2025-13343 can be significant, especially for those in HR, recruitment, and talent acquisition sectors using SourceCodester Interview Management System 1.0. Exploitation could lead to unauthorized access to sensitive candidate information, session hijacking of HR personnel accounts, and potential manipulation of interview questions or candidate data. This undermines confidentiality and integrity of recruitment processes, potentially damaging organizational reputation and compliance with data protection regulations such as GDPR. The attack vector being remote and requiring no authentication increases exposure, while user interaction dependency may limit widespread automated exploitation. However, the public availability of exploit code raises the risk of targeted phishing campaigns. Disruption to recruitment workflows could also indirectly affect business operations. Organizations handling large volumes of personal data or operating in regulated industries face heightened risks of legal and financial penalties if data breaches occur due to this vulnerability.

Summary

CVE-2025-13343 is a cross-site scripting vulnerability identified in SourceCodester Interview Management System version 1.0, located in the /editQuestion.php script. The vulnerability stems from inadequate input validation and sanitization of the 'Question' parameter, which allows an attacker to inject arbitrary JavaScript code. This flaw can be exploited remotely without authentication, although user interaction is necessary for the attack to succeed, typically by tricking a user into clicking a maliciously crafted URL or submitting manipulated input. The vulnerability affects the confidentiality and integrity of user sessions by enabling attackers to steal cookies, perform session hijacking, or execute actions on behalf of the victim. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), and user interaction required (UI:P). The vulnerability does not affect availability or system integrity directly but can lead to further attacks. No official patches or updates have been released by the vendor, and public exploit code is available, increasing the likelihood of exploitation. The vulnerability is particularly relevant for organizations relying on this software for interview and recruitment management, as it could compromise sensitive candidate and organizational data.
