Developed by Dahua Technology, a leading provider of video surveillance products and services, this platform is widely utilized in sectors such as transportation, banking, and retail. It provides functionalities for storing, retrieving, and managing video data, making it crucial for real-time surveillance and investigation. Users of Dahua DSS rely heavily on its capabilities to enhance safety and operational efficiency within their organizations. The platform integrates with various third-party systems, allowing for customizable and scalable security solutions. It is known for its robust performance in handling large volumes of data, which is essential for efficient security operations.

SQL Injection (SQLi) is a critical security vulnerability that allows attackers to interfere with the queries that an application makes to its database. This vulnerability enables malicious users to execute arbitrary SQL code on a vulnerable server, potentially leading to unauthorized access to sensitive data. SQL Injection can affect any database web application that insufficiently or improperly sanitizes user inputs. Attackers exploiting this vulnerability can extract private information, modify database contents, or escalate privileges. Detection and exploitation of SQLI often require minimal technical sophistication, making it a commonly targeted vulnerability. Persisting unchecked, it poses significant security risks to both users and administrators of affected systems.

The vulnerability in Dahua DSS arises from inadequate validation of input data in certain web application endpoints. Specifically, the vulnerable parameters are embedded within GET request paths, such as paths that manage file attachments. These parameters can be manipulated by appending malicious SQL code to extract confidential server data. In particular, the exploitation of this vulnerability involves manipulating database queries using the EXTRACTVALUE function in combination with a concatenated MD5 hash, indicating a flaw in the SQL query parsing logic. The vulnerability requires the server to execute unauthorized code by forcing it to return certain database values, thus compromising data integrity.

If an attacker successfully exploits this SQL Injection vulnerability, it could lead to significant data breaches and unauthorized data access. Sensitive user information and system configurations stored in the database may be exposed or modified, compromising confidentiality and integrity. Furthermore, the attacker might gain elevated privileges, allowing unauthorized actions such as deleting or altering data, stealing credentials, or leveraging the access to infiltrate further into a network. The implications of such exploits can damage organizational reputations, lead to loss of consumer trust, and incur significant financial losses.
