The old mentality of building a moat around important assets and trusting anyone or anything that is already inside the castle perimeter has failed us. Attackers have developed many techniques to jump the moat and scale the castle walls to get at what they want. Thus, the new rallying cry is to implement Zero Trust–the notion that no entity – human or machine, inside or outside the perimeter – should be trusted unconditionally until authenticated,…
What do you know about your APIs? Why are the vulnerable v2 and v3 still exposed if they are deprecated for almost a year? What else is exposed and you don’t even know? Are Swagger specs up to date? (Teaser: Surely not). A lot of questions, right? Meet Wallarm’s latest feature for API Discovery and Observability to better understand and protect your APIs in cloud-native environments – API Security Platform. What is Wallarm API Discovery?…
HTTP/2 become the standard defacto for the modern web and causes new application security risks. The HTTP2 request smuggling is one of a few HTTP/2 vulnerabilities with the high severity that raised last year. In this post, we will describe it in detail and suggest an open-source tool http2smugl that detects such kinds of vulnerabilities. HTTP/2 is the thing that already took an Internet. According to the Wikipedia: “The standardization effort was supported by Chrome,…
Welcome to our weekly exploit digest! We should say this hasn’t been a big week because guys keep producing exploits for the vulnerabilities discovered in the 1st half of March. Nevertheless, we have some new good arrivals for VMware, MS Windows and Win32 to talk about. New 4+ scored exploits have arrived for 7 software titles: VMware View Planner (v4.6) Win32k ConsoleControl Microsoft Exchange 2019 Microsoft Windows Containers DP API SonLogger (v4.2.3.3) LiveZilla Server (v8.0.1.0)…
Welcome to the Wallarm weekly web exploits digest! Since this week, we will publish our weekly digests consists of web exploits with CVSS scores higher than 5. It will be followed by explanations, risks analysis, related stories and news. So, here we go!
The most sophisticated and interesting exploit was out of this score for some reason, but who we are to argue with CVSS score 😉 This is the Apache OFBiz XML-RPC Java Serialization Remote Code Execution issues https://vulners.com/packetstorm/PACKETSTORM:161769 where you can find a XML-packed and Base64 encoded Java deserialization payload:
<name>#{rand_text_alphanumeric(8..42)}</name>
<value>
<serializable xmlns="http://ws.apache.org/xmlrpc/namespaces/extensions">#{Rex::Text.encode_base64(data)}</serializable>
</value>
The recent critical security issue in VMware vCenter was discovered this January and fixed on February 23rd https://www.vmware.com/security/advisories/VMSA-2021-0002.html. The exploit looks like a simple JSP shell upload, but for some reason, it’s a blind spot for Web Application Firewalls (WAFs). Let’s understand why. The CVE-2021-21972 affects vCenter versions 6.5, 6.7, and 7.0. The exploit for Metasploit released https://vulners.com/packetstorm/PACKETSTORM:161695 today. The exploit description is pretty straight forward “This module exploits an unauthenticated OVA file upload and path traversal in VMware…
