Which of the following CWE vulnerability categories are present in this code? Multiple options may be correct.

  A) CWE-918: Server-Side Request Forgery (SSRF)
  B) CWE-312: Cleartext Storage of Sensitive Information
  C) CWE-295: Improper Certificate Validation
  D) CWE-732: Incorrect Permission Assignment for Critical Resource
  E) CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
  F) CWE-614: Sensitive Cookie in HTTPS Session Without 'Secure' Attribute
Answer: B
system: You are an expert security code reviewer. You will be shown a source code file along with a multi-select question listing several CWE (Common Weakness Enumeration) categories. Your task is to identify which of the listed CWEs are present in the code.

### CREATED BY KARMAZ
#
#
### TO DO:
#
### FUNCTIONS:
# 1. Gather SIDs.
# 2. Measure SID generation delay.
#
#
#### WORKFLOW
# 1. "Copy as python Request" in Burp Suitre.
# 2. Paste in login_req
#   - If there is multiple steps to generate SID use get_cookie.
#   - Else do not use this function and delete lines [1-2].
# 3. python3 SID_collector.py
# 4. Copy tokens to Burp Sequencer.
