Microsoft Windows NTLMv2 Hash Disclosure Spoofing Vulnerability — Microsoft Windows contains an NTLMv2 hash spoofing vulnerability that could result in disclosing a user's NTLMv2 hash to an attacker via a file open operation. The attacker could then leverage this hash to impersonate that user. Listed in the CISA KEV catalog (added 2024-11-12) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~84%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Microsoft Windows: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. CISA set a federal remediation due date of 2024-12-03. After patching, verify the vulnerable path is no longer reachable before closing the finding.

An authenticated file read vulnerability in the Palo Alto Networks PAN-OS software enables an authenticated attacker with network access to the management web interface to read files on the PAN-OS filesystem that are readable by the “nobody” user. You can greatly reduce the risk of this issue by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practices deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .

- CVE-2021-21343MED 5.3EPSS 47%
XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability where the processed stream at unmarshalling time contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. An attacker can manipulate the processed input stream and replace or inject objects, that result in the deletion of a file on the local host. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
