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

Exploitation evidence

Detectable: no evidence on record.

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

First, apply strict input validation and sanitization on the message_id parameter to prevent malicious SQL code injection. Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user inputs into SQL commands. Restrict database permissions to the minimum necessary to limit the impact of any successful injection. Monitor web server and database logs for unusual or suspicious queries targeting /deletemessage.php or the message_id parameter. Consider deploying Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts on this endpoint. If possible, isolate or disable the vulnerable functionality temporarily until a vendor patch is released. Conduct thorough security audits and penetration testing focused on SQL injection vectors in the application. Maintain up-to-date backups to enable recovery in case of data compromise. Finally, stay informed about vendor updates or patches and apply them promptly once available.

Description

A security flaw has been discovered in code-projects Nero Social Networking Site 1.0. Affected by this issue is some unknown functionality of the file /deletemessage.php. Performing manipulation of the argument message_id results in sql injection. It is possible to initiate the attack remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations using Nero Social Networking Site 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of user data and platform operations. Exploitation could lead to unauthorized disclosure of private messages or user information, data tampering, or denial of service conditions. This could result in reputational damage, regulatory penalties under GDPR due to data breaches, and operational disruptions. The remote and unauthenticated nature of the exploit increases the attack surface, making it easier for threat actors to target organizations without needing insider access. Social networking platforms are often targeted for data theft and misinformation campaigns, which could have broader societal impacts in Europe. Organizations operating in sectors with high privacy requirements, such as finance, healthcare, or government, are particularly vulnerable to the consequences of this flaw. The public availability of exploit code further elevates the risk of widespread attacks, especially against less-secured or unpatched installations.

Summary

CVE-2025-12308 identifies a SQL injection vulnerability in the Nero Social Networking Site version 1.0, specifically within the /deletemessage.php script. The vulnerability arises from improper sanitization of the message_id parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially extracting sensitive information, modifying or deleting data, or disrupting service availability. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with an attack vector of network (remote), low attack complexity, no privileges or user interaction needed, and impacts on confidentiality, integrity, and availability at a low level. Although no known exploits are currently active in the wild, the public release of exploit code increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the Nero Social Networking Site, a product by code-projects. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts by administrators. This vulnerability is critical for organizations relying on this platform for social networking services, as it could lead to unauthorized data access or manipulation, undermining user trust and regulatory compliance.
