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: 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

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

Organizations should immediately audit and restrict administrative access to the Best House Rental Management System, ensuring only trusted personnel have high privileges. Implement strict input validation and sanitization for all parameters, especially the ID argument in the delete_house function. Where possible, refactor the application code to use parameterized queries or prepared statements to prevent SQL injection. Monitor logs for unusual database queries or failed access attempts that could indicate exploitation attempts. Network segmentation should isolate the rental management system from broader enterprise networks to limit lateral movement. Until an official patch is released, consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this vulnerability. Regularly back up databases and test restoration procedures to mitigate data loss risks. Engage with the vendor or community to track patch availability and apply updates promptly once released.

Description

CVE-2025-12853 is a medium-severity SQL injection vulnerability found in version 1.0 of the SourceCodester Best House Rental Management System. The flaw exists in the delete_house function within the /admin_class.php file, where manipulation of the ID parameter allows an attacker to inject malicious SQL commands. This vulnerability can be exploited remotely without user interaction or authentication, although it requires high privileges. The vulnerability impacts the confidentiality, integrity, and availability of the underlying database, potentially allowing unauthorized data access or modification. No public exploits are currently known in the wild, and no patches have been published yet. European organizations using this software for property management could face data breaches or service disruptions if exploited. Mitigation should focus on input validation, parameterized queries, and restricting access to administrative functions. Countries with higher adoption of SourceCodester products and significant real estate management sectors are at greater risk.

Impact

For European organizations using the SourceCodester Best House Rental Management System, this vulnerability poses risks including unauthorized access to tenant and property data, potential data corruption, and disruption of rental management operations. Confidential information such as tenant identities, rental agreements, and payment details could be exposed or altered, leading to privacy violations and regulatory non-compliance under GDPR. The integrity of rental records may be compromised, affecting business operations and trustworthiness. Availability impacts could result from database manipulation causing service outages or data loss. Given the medium severity and requirement for high privileges, the threat is more significant for organizations with weak internal access controls or insufficient monitoring. The exposure of this vulnerability could also facilitate lateral movement within networks if attackers escalate privileges or pivot from compromised administrative accounts.

Summary

CVE-2025-12853 identifies a SQL injection vulnerability in the SourceCodester Best House Rental Management System version 1.0, specifically in the delete_house function located in /admin_class.php. The vulnerability arises from improper sanitization of the ID parameter, which is used directly in SQL queries. An attacker with high privileges can remotely manipulate this parameter to inject arbitrary SQL commands, potentially leading to unauthorized data retrieval, modification, or deletion within the backend database. The vulnerability does not require user interaction but does require elevated privileges, limiting the attack surface to authenticated administrators or users with similar rights. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H), no user interaction (UI:N), and low impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known public exploits exist, the vulnerability is publicly disclosed, increasing the risk of future exploitation. The absence of patches or mitigations from the vendor increases the urgency for organizations to implement defensive measures. This vulnerability could be leveraged to compromise sensitive rental data, disrupt service availability, or escalate privileges within the application environment.
