CVE-2020-6012 (GCVE-0-2020-6012)

Vulnerability from cvelistv5 – Published: 2020-08-04 13:35 – Updated: 2024-08-04 08:47
VLAI
Summary
ZoneAlarm Anti-Ransomware before version 1.0.713 copies files for the report from a directory with low privileges. A sophisticated timed attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links. This allows an unprivileged user to enable escalation of privilege via local access.
Severity
No CVSS data available.

Title
Cisco SD-WAN vManage Software Information Disclosure Vulnerability
Summary
A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to read arbitrary files on the underlying filesystem of the device. The vulnerability is due to insufficient file scope limiting. An attacker could exploit this vulnerability by creating a specific file reference on the filesystem and then accessing it through the web-based management interface. A successful exploit could allow the attacker to read arbitrary files from the filesystem of the underlying operating system.

Title
Cisco AnyConnect Secure Mobility Client for Mac OS File Corruption Vulnerability
Summary
A vulnerability in the uninstaller component of Cisco AnyConnect Secure Mobility Client for Mac OS could allow an authenticated, local attacker to corrupt the content of any file in the filesystem. The vulnerability is due to the incorrect handling of directory paths. An attacker could exploit this vulnerability by creating a symbolic link (symlink) to a target file on a specific path. A successful exploit could allow the attacker to corrupt the contents of the file. If the file is a critical systems file, the exploit could lead to a denial of service condition. To exploit this vulnerability, the attacker would need to have valid credentials on the system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Title
Cisco IOx Application Framework Arbitrary File Overwrite Vulnerability
Summary
A vulnerability in the Cisco Application Framework component of the Cisco IOx application environment could allow an authenticated, local attacker to overwrite arbitrary files in the virtual instance that is running on the affected device. The vulnerability is due to insufficient path restriction enforcement. An attacker could exploit this vulnerability by including a crafted file in an application package. An exploit could allow the attacker to overwrite files.

Mitigation MIT-48.1
Architecture and Design

Strategy: Separation of Privilege

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack

An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-35: Leverage Executable Code in Non-Executable Files

An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
