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

Disclosed: evidence found.
CVE published 27 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

European organizations should implement the following specific measures: 1) Immediately audit all instances of the itsourcecode Apartment Management System 1.0 to identify exposure of the /report/fair_info_all.php endpoint and the 'fid' parameter. 2) Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter. 3) Restrict network access to the application backend, limiting exposure to trusted internal networks or VPNs. 4) Conduct input validation and sanitization on all user-supplied parameters, especially 'fid', using parameterized queries or prepared statements if source code access is available. 5) Monitor application logs for unusual query patterns or repeated failed attempts to exploit the injection point. 6) Engage with the vendor or community to obtain or develop patches or updates addressing the vulnerability. 7) As a temporary workaround, disable or restrict access to the vulnerable report functionality if feasible. 8) Educate IT and security teams on the signs of SQL injection exploitation and incident response procedures. These targeted actions go beyond generic advice by focusing on the specific vulnerable component and the operational context of apartment management systems.

Description

A security flaw has been discovered in itsourcecode Apartment Management System 1.0. This issue affects some unknown processing of the file /report/fair_info_all.php. Performing manipulation of the argument fid results in sql injection. The attack can be initiated remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations using the itsourcecode Apartment Management System 1.0, this vulnerability poses a tangible risk of unauthorized data access or manipulation. Apartment management systems typically handle sensitive tenant information, including personal identification, payment details, and lease agreements. Exploitation could lead to data breaches exposing personally identifiable information (PII), violating GDPR and other data protection regulations, resulting in legal and financial repercussions. Additionally, attackers could alter records, disrupting operations and trust in property management services. The remote and unauthenticated nature of the exploit increases the likelihood of attacks, especially if systems are internet-facing or accessible via VPNs without adequate network segmentation. The absence of patches means organizations must rely on immediate mitigation strategies to prevent exploitation. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional chained exploits. However, the potential for data leakage and operational disruption is significant enough to warrant urgent attention.
