CVE-2025-0674 Scanner

Elber ESE DVB-S/S2 is a satellite equipment product employed by companies for broadcast and communication solutions, supporting a range of satellite modulation standards for various professional applications. It is widely used by broadcasters and service providers for signal reception and transmission. The product includes management interfaces accessible via network connections to configure and oversee device settings. Users leverage the DVB-S/S2 standards to transmit audio and video data efficiently across large geographical areas. The software enables users to perform diverse tasks including channel reception, decryption, and re-encoding services. Elber products are a crucial component in the chain for ensuring uninterrupted satellite broadcast services.

The vulnerability identified within Elber ESE DVB-S/S2 pertains to an authentication bypass flaw. It allows attackers to exploit access controls, potentially enabling unauthorized users to access sensitive areas of the application. By circumventing authentication mechanisms, unauthorized actors can change user credentials, thereby escalating privileges within the system. This security gap is critical as it undermines the integrity and confidentiality of the entire setup. The exploitation requires knowledge of specific endpoint manipulation which attackers could utilize to alter administrative settings. The vulnerability could thus lead to potential system compromise.

The technical detail of the vulnerability manifests within the password management module of the system. Attackers can send crafted HTTP requests to endpoints like `/modules/pwd.html` to manipulate password settings without proper authorization. The request `GET /json_data/set_pwd?lev=2&pass=admin1234` indicates a misuse where control over the password system is gained. Access to these endpoints is not adequately protected against unauthorized access attempts. The flaw lies in the inadequate authentication checks at critical stages of password management interactions. These endpoints allow parameter alteration, providing attackers a pathway to gain control over system-level access.

Exploiting this vulnerability could result in unauthorized administrative control, leading to potential full system access by malicious entities. It can compromise sensitive data through unauthorized password reset or alterations. There is an elevated risk of further attacks, including the deployment of malicious software or data corruption. Unchecked exploitation could disrupt operations, rendering critical satellite communications compromised. This could also lead to economic losses and reputation damage for companies relying on Elber products for their broadcast needs. In the worst scenario, attackers could manipulate broadcast signals and server operations.
