Cache Control vulnerability

In short, websites are vulnerable to web cache poisoning if they handle unkeyed input in an unsafe way and allow the subsequent HTTP responses to be cached. This vulnerability can be used as a delivery method for a variety of different attacks. Using web cache poisoning to deliver an XSS attac Cache-control: no-cache The no-cache attribute indicates that the browser should not use the information that is cached for that particular request-response pair. The browser stores the cache, but instead of showing the content from the cache, it sends the request to the server each time

Cache-Control: No-Store The no-store directive means browsers aren't allowed to cache a response and must pull it from the server each time it's requested. This setting is usually used for sensitive data, such as personal banking details The Cache-Control HTTP header holds directives (instructions) for caching in both requests and responses. A given directive in a request does not mean the same directive should be in the response But generally, use both Cache-Control: no-cache, no-store and Pragma: no-cache, Buffer overflow vulnerability affects the web applications that require user input. The application stores the input in a buffer which is of a fixed size, as defined by the programmer. When the input that is sent to the application is more than the buffer. Cache-Control is a powerful HTTP header when it comes to speeding up websites with the use of browser and intermediary cache. Although its ability to increase website speed is not it's only as it is also quite useful to help make private information less vulnerable Without cache control settings, the browser goes to the web server for every request for resources and reads information from it. This increases load times of the affected site, adds extra load to..

The problem is with ALL static files we placed in Amazon S3 that's being accessed through CloudFront CDN. We can access the files fine (and no issue with CORS), but apparently CloudFront doesn't serve files with Cache-Control header

Cache Poisoning Software Attack OWASP Foundatio

  1. Cache-Control: public. HTTP 1.1 introduced an array of cache control directives. These give greater flexibility and control to the developer. The cache-control: public directive is the most basic directive and tells the browser and proxies in the path that the page may be cached. This is good for non-sensitive pages, as caching improves.
  2. If sensitive information in application responses is stored in the local cache, then this may be retrieved by other users who have access to the same computer at a future time. Remediation: Cacheable HTTPS response Applications should return caching directives instructing browsers not to store local copies of any sensitive data
  3. Cisco's Cisco Cache Engine product provides transparent caching for world-wide web pages retrieved via HTTP.

Some of these headers contain content meta data such as the Content-Encoding, Cache-Control, status codes, etc. Along with these are also HTTP security headers that tell your browser how to behave when handling your website's content. For example, by using the Strict-Transport-Security you can force the browser to communicate solely over HTTPS. A Cookie Vulnerability helps an attacker to gain access to session information stored in cookies. It may also be used as a 'locator' attack that precedes a Cross-Site Scripting (XSS) or Man-In-The-Middle attack. When lookin An attacker sends a GIF or an image to a victim and gets control over their account. This vulnerability worked just that way and had the potential to take over an organization's entire roster of Microsoft Teams accounts

The first vulnerability was a CRLF injection in the page_id parameter on https://repo.org.github.io/__/auth. Perhaps the best way to find vulnerabilities is to play around. As part of my investigation into the authentication flow, I noticed that the page_id parsing seemed to ignore whitespace Cache-Control. Here we look at Cache-Control headers in ASP.NET. The implementation of caching on Response.Cache is complex and confusing in ASP.NET. Some options will trigger other options. These interactions are hard to understand. Tip Setting a page for 1 hour of caching is done in this code. Cache-Control helps browsers with conditional. A negative value for expires automatically sends a Cache-Control: no-cache in the response, thus deactivating the cache. There is no need to manually add a Last-Modified header in the config as Nginx automatically sets it with the last modification date of the resource on the file system
