CVE-2024-44065 identifies a time-based blind SQL Injection vulnerability in Cloudlog version 2.6.15, located at the /index.php/logbookadvanced/search endpoint, specifically through the qsoresults parameter. Time-based blind SQL Injection is a technique where an attacker sends crafted SQL queries that cause the database to delay its response based on the evaluation of injected conditions. By measuring these delays, the attacker can infer sensitive information from the database without direct output. This vulnerability allows attackers to extract data, manipulate database contents, or escalate privileges by exploiting the lack of proper input sanitization or parameterization in the affected endpoint. Cloudlog is an open-source logging application primarily used by amateur radio operators to manage and log contacts (QSOs). While no patches or fixes have been published yet, the vulnerability's presence in a widely used endpoint means that attackers could leverage it to access sensitive user data or disrupt operations. The absence of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed, but the technical nature of time-based blind SQL Injection typically implies a significant risk. No known exploits are currently in the wild, but the potential for exploitation exists, especially if attackers develop automated tools targeting this flaw. The vulnerability's impact extends to confidentiality and integrity of data stored in the Cloudlog database, with possible indirect effects on availability if the database is manipulated or corrupted.

For European organizations using Cloudlog, particularly amateur radio clubs, hobbyists, or communication-focused entities, this vulnerability could lead to unauthorized disclosure of sensitive contact logs and personal information. The compromise of database integrity could result in falsified or deleted records, undermining trust in the logging system. Although Cloudlog is niche software, its users may include critical communication stakeholders or enthusiasts who maintain important historical or operational data. Exploitation could also serve as a foothold for further attacks within organizational networks if the compromised system is connected to broader infrastructure. The lack of public exploits currently reduces immediate risk, but the vulnerability's nature means that once exploited, it could have severe consequences for data confidentiality and integrity. European organizations may face compliance and reputational risks if personal data is exposed due to this flaw. The impact is heightened in countries with larger amateur radio communities or where Cloudlog adoption is more prevalent.

Until an official patch is released, organizations should implement strict input validation and sanitization on the qsoresults parameter and any other user-supplied inputs in Cloudlog. Employing web application firewalls (WAFs) with rules to detect and block SQL Injection patterns, especially time-based payloads, can provide a temporary protective layer. Reviewing and hardening database permissions to limit the impact of potential SQL Injection is critical—restricting the database user to only necessary privileges reduces damage scope. Monitoring logs for unusual query patterns or delays can help detect exploitation attempts early. Organizations should also consider isolating Cloudlog instances from critical network segments to contain potential breaches. Once a patch is available, prompt application is essential. Additionally, educating users about the risks and encouraging minimal exposure of the affected endpoint to untrusted networks can reduce attack surface.
