Zoho patches a newly disclosed high-severity SQL injection flaw in several ManageEngine products; attackers have historically targeted several ManageEngine products over the last three years.

Background

On December 29, Zoho’s ManageEngine published an advisory for a newly disclosed vulnerability in its Password Manager Pro, PAM360 and Access Manager Plus products.

Analysis

CVE-2022-47523 is a SQL injection (SQLi) vulnerability in ManageEngine Password Manager Pro, PAM360 and Access Manager Plus. The vulnerability exists due to the improper validation of user-supplied input. An attacker could exploit this flaw by sending a specially crafted request to a vulnerable server. Successful exploitation would allow an attacker to execute arbitrary queries and read or modify database table entries. While ManageEngine did not assign a CVSSv3 score for the flaw at the time this post was published, they did categorize the severity of the flaw as High, and advised that its customers update affected products immediately.

In September 2022, ManageEngine patched CVE-2022-40300, which they classified as “multiple SQL injection vulnerabilities” in the same products as CVE-2022-47523. Researchers at Trend Micro’s Zero Day Initiative published a blog post based on a writeup for CVE-2022-40300.

Interestingly, ManageEngine included a message in its advisory for CVE-2022-47523 that, due to the severity of the vulnerability, customers should apply patches immediately; however no such message appeared in its advisory for CVE-2022-40300.
