FAQ for SMB Pathname Overflow Vulnerability - CVE-2010-0020
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system.
What is the CVE ID for this specific vulnerability? ›
A CVE Identifier is a unique number assigned to a specific security vulnerability, formatted as CVE-[Year]-[Number]. Assigned by CVE Numbering Authorities (CNAs), these identifiers help standardize the tracking and management of vulnerabilities across the cybersecurity community.
Vulnerability scanning is the process of identifying security weaknesses and flaws in systems and software running on them. This is an integral component of a vulnerability management program, which has one overarching goal – to protect the organization from breaches and the exposure of sensitive data.
What is BlueKeep vulnerability? ›
BlueKeep is a software vulnerability affecting older versions of Microsoft Windows. Its risk is significant because it attacks an operating system's Remote Desktop Protocol (RDP), which connects to another computer over a network connection. This would allow a cyberthreat to spread very quickly.
What is netlogon vulnerability? ›
The flaw in Netlogon allows an unauthenticated attacker on an internal network to connect to the domain controller and set a new computer password. The attacker can then use this new password to take over the domain controller and, from there, gain control of the Windows network.
What is secondary logon elevation of privilege vulnerability? ›
Description. An elevation of privilege vulnerability exists in Microsoft Windows if the Windows Secondary Logon Service fails to properly manage request handles in memory. An attacker who successfully exploited this vulnerability could run arbitrary code as an administrator.
What is suspected netlogon privilege elevation attempt? ›
This vulnerability allows an attacker to escalate privileges to a domain administrator level by exploiting a flaw in the Netlogon Remote Protocol. Microsoft Defender for Identity can detect attempts to exploit this vulnerability.
Is CVE a vulnerability? ›
CVE stands for Common Vulnerabilities and Exposures. CVE is a glossary that classifies vulnerabilities. The glossary analyzes vulnerabilities and then uses the Common Vulnerability Scoring System (CVSS) to evaluate the threat level of a vulnerability.
Which vulnerabilities qualify for a CVE? ›
There are certain criteria to be satisfied to assign a CVE ID to a vulnerability:
- The vulnerability should have a negative impact on security.
- The vulnerability can be fixed independently.
- The vulnerability impacts only one product. (It will get a separate CVE ID if it affects more than one.)
An unauthenticated, unauthorized attacker sending a specially crafted MMS to a vulnerable phone can trigger a heap-based buffer overflow in the Quram image codec leading to an arbitrary remote code execution (RCE) without any user interaction.
What is the CVE 2020 0688 vulnerability? ›
Description. A remote code execution vulnerability exists in Microsoft Exchange software when the software fails to properly handle objects in memory, aka 'Microsoft Exchange Memory Corruption Vulnerability'.
