CVE-2026-77966
HighCVSS 8.8Summary
The affected Ebyte product does not provide separation between limited and administrative management functions. A low privileged authenticated attacker could access security sensitive configuration functions and modify settings affecting confidentiality, integrity, or availability.
Risk Assessment
An authenticated attacker could change critical security settings, potentially leading to compromise of confidentiality, integrity, or availability.
Recommendation
Implement proper access control mechanisms to separate administrative functions from limited ones, and restrict user privileges.
Other vulnerabilities in Ebyte product
See all- CVE-2026-77975Medium
The affected Ebyte product exports administrative credentials and other sensitive configuration information without adequate protection. An unauthenticated attacker on the adjacent network who obtains an exported configuration file could recover valid credentials and use them to access the device or similarly configured systems.
- CVE-2026-76133Critical
The affected Ebyte product uses a deprecated hashing algorithm in an authentication-related operation. Under conditions where an attacker can manipulate or predict the authentication exchange, the weak construction may reduce the assurance provided by the authentication mechanism and facilitate unauthorized access.
- CVE-2026-73819Critical
The affected Ebyte product's vendor configuration utility permits access to administrative functions without verifying the operator's identity under certain credential conditions. An unauthenticated attacker on the adjacent network could modify critical settings or change access credentials, potentially preventing legitimate administrators from managing the device.
