In Team82's joint research with Snyk, we examined 16 URL parsing libraries, written in a variety of programming languages, and noticed some inconsistencies with how each chooses to parse a given URL to its basic components. We categorized the types of inconsistencies into five categories, and searched for problematic code flows in web applications and open source libraries that exposed a number of vulnerabilities.
CWE-36: Absolute Path Traversal
Successful exploitation of this vulnerability could allow an attacker to read from the Experion controllers or SMSC S300. This exploit could be used to read files from the controller that may expose limited information from the device.
CVSS v3: 5.3
CWE-749: Exposed Dangerous Method or Function
Successful exploitation of this vulnerability could allow an attacker to modify files on Experion controllers or SMSC S300. This exploit could be used to write a file that may result in unexpected behavior based on configuration changes or updating of files that could result in subsequent execution of a malicious application if triggered.
CVSS v3: 9.1
CWE-284 IMPROPER ACCESS CONTROL:
The entire parent directory - C:\ScadaPro and its sub-directories and files are configured by default to allow users, including unprivileged users, to write or overwrite files.
Measuresoft recommends that users manually reconfigure the vulnerable directories so that they are not writable by everyone.
CVSS v3: 5.5
CWE-256: Plaintext Storage of a Password
In Automation-Direct C-MORE EA9 HMI credentials used by the platform are stored as plain text on the device.
AutomationDirect recommends that users update C-MORE EA9 HMI to V6.78
Affected versions:
CVSS v3: 6.5
CWE-121: Stack-based Buffer Overflow
In Automation-Direct C-MORE EA9 HMI there is a program that copies a buffer of a size controlled by the user into a limited sized buffer on the stack which leads to a stack overflow. The result of this stack-based buffer overflow will lead to a denial-of-service conditions.
AutomationDirect recommends that users update C-MORE EA9 HMI to V6.78
Affected versions:
CVSS v3: 4.3
