Rewterz Threat Advisory – CVE-2019-3462 – Critical flaw in Linux APT Package Manager could Allow Remote Hack

SEVERITY: High

 

 

CATEGORY: Vulnerability

 

 

ANALYSIS SUMMARY

 

 

While using apt-get command, HTTP redirects allow Linux systems to automatically request packages from a mirror server when others are unavailable. When the first server is not able to provide the package, it responds by providing the next suitable server.

 

The code handling HTTP redirects in the HTTP transport method doesn’t properly sanitize fields transmitted over the wire. This vulnerability could be used by an attacker located as a man-in-the-middle between APT and a mirror to inject malicious content in the HTTP connection.

 

 

IMPACT

 

 

Content injection in http method.

 

 

AFFECTED PRODUCTS 

 

 

APT Packet Manager 0.8.15
