In a joint effort, CISA and the FBI have issued a call to technological companies to reevaluate their software to prevent XSS vulnerabilities in future releases. The vulnerability of the intersight script continues to pose a problem for numerous modern products, highlighting the importance of adhering to appropriate development standards to avoid such issues.
The agencies have underlined that XSS vulnerabilities provide attackers with added avenues for carrying out attacks, including the insertion of malicious scripts into web applications. This can result in data manipulation, theft, or unauthorized use in various scenarios, all stemming from errors in input data verification, cleaning, and shielding.
CISA and the FBI representatives have advised that technological company managers conduct formal audits to incorporate secure development principles that would effectively eliminate XSS vulnerabilities. Additionally, the agencies have cautioned that data cleansing methods alone may not suffice in thwarting threats, stressing the need for extra security measures such as examining input data structure and content, alongside employing modern web frameworks with filtering and encoding functions.
To enhance code safety, specialists from CISA and the FBI recommend thorough audits and testing across the entire software development lifecycle. Such proactive measures can help prevent vulnerabilities in upcoming software releases. According to MITRE, XSS vulnerabilities rank second among the most perilous software vulnerabilities , trailing behind issues like “out-of-bounds” vulnerabilities.
