CVE-2021-23886

Denial of Service vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.100 allows a local, low privileged, attacker to cause a BSoD through suspending a process, modifying the processes memory and restarting it. This is triggered by the hdlphook driver reading invalid memory.

CVE-2021-23887

Privilege Escalation vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.100 allows a local, low privileged, attacker to write to arbitrary controlled kernel addresses. This is achieved by launching applications, suspending them, modifying the memory and restarting them when they are monitored by McAfee DLP through the hdlphook driver.

CVE-2020-7308

Cleartext Transmission of Sensitive Information between McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2021 Update and McAfee Global Threat Intelligence (GTI) servers using DNS allows a remote attacker to view the requests from ENS and responses from GTI over DNS. By gaining control of an intermediate DNS server or altering the network DNS configuration, it is possible for an attacker to intercept requests and send their own responses.

CVE-2020-7270

Exposure of Sensitive Information in the web interface in McAfee Advanced Threat Defense (ATD) prior to 4.12.2 allows remote authenticated users to view sensitive unencrypted information via a carefully crafted HTTP request parameter. The risk is partially mitigated if your ATD instances are deployed as recommended with no direct access from the Internet to them.

CVE-2021-27850

A critical unauthenticated remote code execution vulnerability was found all recent versions of Apache Tapestry. The affected versions include 5.4.5, 5.5.0, 5.6.2 and 5.7.0. The vulnerability I have found is a bypass of the fix for CVE-2019-0195. Recap: Before the fix of CVE-2019-0195 it was possible to download arbitrary class files from the classpath by providing a crafted asset file URL. An attacker was able to download the file `AppModule.class` by requesting the URL `http://localhost:8080/assets/something/services/AppModule.class` which contains a HMAC secret key. The fix for that bug was a blacklist filter that checks if the URL ends with `.class`, `.properties` or `.xml`. Bypass: Unfortunately, the blacklist solution can simply be bypassed by appending a `/` at the end of the URL: `http://localhost:8080/assets/something/services/AppModule.class/` The slash is stripped after the blacklist check and the file `AppModule.class` is loaded into the response. This class usually contains the HMAC secret key which is used to sign serialized Java objects. With the knowledge of that key an attacker can sign a Java gadget chain that leads to RCE (e.g. CommonsBeanUtils1 from ysoserial). Solution for this vulnerability: * For Apache Tapestry 5.4.0 to 5.6.1, upgrade to 5.6.2 or later. * For Apache Tapestry 5.7.0, upgrade to 5.7.1 or later.
