XSS IN COMMENT SECTION

Vulnerabilities and Recommendations:

MS14-066: Vulnerability in Schannel Could Allow Remote Code Execution - The remote Windows host is affected by a remote code execution vulnerability due to improper processing of packets by the Secure Channel (Schannel) security package. An attacker can exploit this issue by sending specially crafted packets to a Windows server.

• Microsoft has released a set of patches for Windows 7, 2008 R2, 8, 8.1, 2012, and 2012 R2

MS15-034: Vulnerability in HTTP.sys Could Allow Remote Code Execution - The version of Windows running on the remote host is affected by an integer overflow condition in the HTTP protocol stack (HTTP.sys) due to improper parsing of crafted HTTP requests. An unauthenticated, remote attacker can exploit this to execute arbitrary code with System privileges.

• Microsoft has released a set of patches for Windows 7, 2008 R2, 8, 8.1, 2012, and 2012 R2

SQL Injection

• Constrain and sanitize input data.
  • Check for known good data by validating for type, length, format, and range.

Use type-safe SQL parameters for data access

• Use an account that has restricted permissions in the database.

  • Only grant execute permissions to selected stored procedures in the database and provide no direct table access.

• Avoid disclosing database error information.

  • Use these parameters with stored procedures or dynamically constructed SQL command strings.
