CWE	CWE-327: Use of a Broken or Risky Cryptographic Algorithm
OWASP	A03:2017 - Sensitive Data Exposure
Confidence Level	Medium
Impact Level	Medium
Likelihood Level	Medium

Description#

The code uses the IDEA (International Data Encryption Algorithm) cipher, which is outdated and known to be vulnerable when weak keys are used. This makes encrypted data easier to break compared to modern encryption algorithms.

Impact#

Attackers could exploit weaknesses in IDEA to decrypt sensitive information, potentially leading to data breaches and exposure of confidential data. This undermines the security of the application and can result in regulatory or reputational damage.
