Executive brief
MIA Technology's Pizzy Library contains a security flaw that allows malicious code to be embedded within exported CSV files. If an employee or customer opens one of these files in a spreadsheet application like Microsoft Excel, the malicious code could execute on their computer, potentially leading to data theft or unauthorized system access. This poses a significant risk to data integrity and the security of workstations interacting with exported reports.
Technical details
The Pizzy Library by MIA Technology Inc. is vulnerable to CWE-1236 (Improper Neutralization of Formula Elements in a CSV File). The vulnerability exists because the library fails to properly sanitize input that is later exported into CSV format, allowing the inclusion of spreadsheet formulas (e.g., starting with =, +, -, or @). An attacker with low-level privileges can inject malicious formulas that, when opened by a victim in a spreadsheet application, can execute arbitrary commands or exfiltrate sensitive data via DDE (Dynamic Data Exchange). The issue affects versions 1.0.0.26250 through 1.3.9.26250.
