CVE-2020-7982

Severity CVSS v4.0:
Pending analysis
Type:
CWE-345 Insufficient Verification of Data Authenticity
Publication date:

Description

An issue was discovered in OpenWrt 18.06.0 to 18.06.6 and 19.07.0, and LEDE 17.01.0 to 17.01.7. A bug in the fork of the opkg package manager before 2020-01-25 prevents correct parsing of embedded checksums in the signed repository index, allowing a man-in-the-middle attacker to inject arbitrary package payloads (which are installed without verification).
