SEC0026 identifies usage of the weak Cipher Modes in symmetric encryption operations including CFB, CTS, ECB, and OFB. Weaknesses in the Cipher Mode can allow cryptographic attacks to compromise the integrity or confidentiality of data.
Symmetric algorithms use a Cipher Mode to repeatedly apply a cryptographic transformation to multiple blocks of data. The following methods are included in the ‘bypassSecurityTrust’ family: If these functions must be used, ensure the data being passed into them poses no security risk. Data passed to the ‘bypassSecurityTrust’ family of functions will be written to the browser unencoded potentially exposing Angular applications to DOM based Cross-Site Scripting attacks.Įvaluate each use of the ‘bypassSecurityTrust’ function and determine if absolutely necessary. The ‘bypassSecurityTrust’ family of functions exist to allow developers to circumvent Angular’s built-in sanitization functions. Alternatively, ensure data is properly encoded prior to binding to the ‘dangerouslySetInnerHTML’ property.ĬWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

However, if you have to bind data to innerHTML, ensure the data is from a trusted source, it cannot be manipulated in transit, and potentially executable code is rendered harmless. Use the recommended data binding method of “” within HTML tags. Data bound directly to an Element.innerHTML property will be written to the browser unencoded potentially resulting in Cross-Site Scripting (XSS) vulnerabilities if the data source is considered untrusted or dynamic (request parameters, database, web service, etc.). React’s ‘dangerouslySetInnerHTML’ allows data to be directly bound to an element’s innerHTML property.
