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

CVE published 1 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 2026-10-26.

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 their use of SourceCodester Hotel Reservation System 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement web application firewall (WAF) rules specifically targeting SQL injection patterns on the /admin/updateabout.php endpoint and the 'address' parameter. Employ input validation and parameterized queries or prepared statements in the application code to prevent injection. Restrict access to the /admin directory via IP whitelisting or VPN to reduce exposure. Conduct thorough logging and monitoring for unusual database queries or access patterns. Regularly back up databases to enable recovery in case of data tampering. Finally, perform security awareness training for administrators to recognize and respond to suspicious activity promptly.

Description

A security flaw has been discovered in SourceCodester Hotel Reservation System 1.0. This affects an unknown part of the file /admin/updateabout.php. The manipulation of the argument address results in sql injection. The attack may be launched remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations operating or using the SourceCodester Hotel Reservation System 1.0, this vulnerability poses a significant risk to customer data confidentiality and system integrity. Exploitation could lead to unauthorized disclosure of personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, attackers could alter reservation data or disrupt booking operations, impacting business continuity. Given the hospitality sector's reliance on trust and data privacy, a breach could lead to loss of customer confidence and financial losses. The remote and unauthenticated nature of the exploit increases the threat level, especially for smaller hotels or chains that may lack robust cybersecurity defenses. Furthermore, the public availability of exploit code lowers the barrier for attackers, potentially increasing attack volume and impact across Europe.

Summary

CVE-2025-9790 is a SQL Injection vulnerability identified in SourceCodester Hotel Reservation System version 1.0. The flaw exists in the /admin/updateabout.php script, specifically in the handling of the 'address' parameter. An attacker can manipulate this parameter to inject malicious SQL code, which the backend database executes. This vulnerability is remotely exploitable without requiring authentication or user interaction, making it particularly dangerous. The injection can lead to unauthorized data access, data modification, or potentially full compromise of the database. The CVSS 4.0 score of 6.9 (medium severity) reflects the ease of exploitation (network vector, no privileges or user interaction needed) but limited impact on confidentiality, integrity, and availability (low to limited impact). However, the vulnerability's presence in a hotel reservation system is critical because such systems typically store sensitive customer data including personal identification and payment information. The lack of a patch or mitigation details increases risk, especially since the exploit code has been publicly released, raising the likelihood of exploitation by opportunistic attackers.
