Successful exploitation of these vulnerabilities could allow access to sensitive information.
The following versions of GE Digital APM Classic, a tool to analyze and process data, are affected:
An insecure direct object reference (IDOR) vulnerability allows user account data to be downloaded in JavaScript object notation (JSON) format by users who should not have access to such functionality. An attacker can download sensitive data related to user accounts without having the proper privileges.
CVE-2020-16240 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
Salt is not used for hash calculation of passwords, making it possible to decrypt passwords. This design flaw, along with the IDOR vulnerability, puts the entire platform at high risk because an authenticated user can retrieve all user account data and then retrieve the actual passwords.
CVE-2020-16244 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Guido Marilli of Accenture Security reported these vulnerabilities to GE Digital.
