Details and a proof-of-concept exploit have been released for an unpatched privilege escalation vulnerability in Windows related to the PsExec administration tool. According to Wells, the vulnerability is a local privilege escalation issue that can be exploited by a non-admin process to elevate privileges to SYSTEM when PsExec is executed remotely or locally on the targeted computer.

A day after proof-of-concept exploit code was published for a critical flaw in Cisco Security Manager, Cisco has hurried out a patch. PoC exploits for the flaw - as well as 11 other issues in Cisco Security Manager - were published online Monday by security researcher Florian Hauser.

Cisco has patched two vulnerabilities in its Cisco Security Manager solution, both of which could allow unauthenticated, remote attackers to gain access to sensitive information on an affected system. Those are part of a batch of twelve vulnerabilities flagged in July 2020 by Florian Hauser, a security researcher and red teamer at Code White.

Attacked by ransomware? Five steps to recoveryWhile there is a lot of discussion about preventing ransomware from affecting your business, the best practices for recovering from an attack are a little harder to pin down. Justifying your 2021 cybersecurity budgetSitting in the midst of an unstable economy, a continued public health emergency, and facing an uptick in successful cyber attacks, CISOs find themselves needing to enhance their cybersecurity posture while remaining within increasingly scrutinized budgets.

Have you already updated your Apache Struts 2 to version 2.5.22, released in November 2019? You might want to, and quickly, as information about a potential RCE vulnerability and PoC exploits for it have been published. "We continue to urge developers building upon Struts 2 to not use % syntax referencing unvalidated user modifiable input in tag attributes, since this is the ultimate fix for this class of vulnerabilities," René Gielen, Struts Project Management Committee chair, added.

Proof-of-concept exploit code surfaced on GitHub on Friday, raising the stakes on two existing Apache Struts 2 bugs that allow for remote code-execution and denial-of-service attacks on vulnerable installations. Remediation includes upgrading to Struts 2.5.22, according to the Apache Struts Security Team.

Details and PoC for critical SharePoint RCE flaw releasedA "Wormable" remote code execution flaw in the Windows DNS Server service temporarily overshadowed all the other flaws patched by Microsoft on July 2020 Patch Tuesday, but CVE-2020-1147, a RCE affecting Microsoft SharePoint, was also singled out as critical and requiring a speedy fix. Microsoft releases new encryption, data security enterprise toolsMicrosoft has released several new enterprise security offerings to help companies meet the challenges of remote work.

Tracked as CVE-2020-1147 and considered critical severity, the bug occurs when the software doesn't check the source markup of XML file input. "The vulnerability is found in the DataSet and DataTable types which are.NET components used to manage data sets," the software giant revealed in an advisory published last week.

Last week, a "Wormable" remote code execution flaw in the Windows DNS Server service temporarily overshadowed all the other flaws patched by Microsoft on July 2020 Patch Tuesday, but CVE-2020-1147, a RCE affecting Microsoft SharePoint, was also singled out as critical and requiring a speedy fix. Implementing the offered security updates has since become even more urgent, as more exploitation details and a PoC have been released on Monday.

A security researcher has published a PoC RCE exploit for SMBGhost, a wormable flaw that affects SMBv3 on Windows 10 and some Windows Server versions. The PoC exploit is unreliable, but could be used by malicious attackers as a starting point for creating a more effective exploit.
