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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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

To mitigate this vulnerability, organizations should implement strict input validation and output encoding on the 'car_name' parameter within the /admin/add_vehicles.php script. Specifically, all user-supplied data should be sanitized to remove or encode HTML special characters to prevent script injection. Employing a web application firewall (WAF) with rules to detect and block XSS payloads targeting this endpoint can provide an additional layer of defense. Restricting access to the administrative interface through network segmentation, VPNs, or IP whitelisting will reduce exposure to remote attackers. Administrators should be trained to recognize suspicious links or inputs that could trigger XSS attacks. Regular security assessments and penetration testing focusing on the admin interface can help identify residual or related vulnerabilities. Finally, monitoring logs for unusual activity around the /admin/add_vehicles.php endpoint can aid in early detection of exploitation attempts.

Description

A vulnerability, which was classified as problematic, has been found in code-projects Simple Car Rental System 1.0. This issue affects some unknown processing of the file /admin/add_vehicles.php. The manipulation of the argument car_name leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using the Simple Car Rental System version 1.0, this vulnerability poses a risk primarily to the integrity of the administrative interface. Successful exploitation could allow attackers to execute arbitrary scripts in the context of an administrator's browser session, potentially leading to session hijacking, unauthorized actions within the admin panel, or distribution of malware to other users. While the vulnerability does not directly compromise confidentiality or availability, the indirect effects could include unauthorized modification of vehicle data or rental records, undermining business operations and trust. Given the nature of the application—car rental management—such disruptions could affect customer service and operational continuity. Additionally, regulatory frameworks such as GDPR require organizations to maintain secure processing of personal data; exploitation of this vulnerability could lead to data integrity issues and potential compliance violations if personal data is manipulated or exposed through subsequent attacks. The medium severity score suggests that while the threat is not critical, it should be addressed promptly to prevent exploitation, especially in environments where the administrative interface is exposed or accessible over the internet.

Summary

CVE-2025-8337 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the Simple Car Rental System developed by code-projects. The vulnerability arises from improper handling of the 'car_name' parameter in the /admin/add_vehicles.php script. Specifically, the application fails to adequately sanitize or encode user-supplied input for this parameter, allowing an attacker to inject malicious scripts. This vulnerability is exploitable remotely without authentication, although it requires user interaction to trigger the malicious payload. The CVSS 4.0 base score is 4.8, indicating a medium severity level. The vector string indicates that the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:H indicates high privileges, but this conflicts with the description; likely a data inconsistency), and user interaction is required (UI:P). The impact on confidentiality is none, integrity is low, and availability is none. The vulnerability does not affect system confidentiality or availability but can impact integrity by enabling script injection that could lead to session hijacking, defacement, or redirection to malicious sites. No patches or known exploits in the wild have been reported yet. The vulnerability disclosure date is July 30, 2025. Given that the affected component is an administrative interface, exploitation could lead to significant impacts if an attacker successfully convinces an administrator to interact with a crafted link or input, potentially compromising administrative sessions or injecting malicious scripts into the admin panel interface.
