Cybersecurity Alerts

Cisco IOS XE contains a command injection vulnerability in the web user interface. When chained with CVE-2023-20198, the attacker can leverage the new local user to elevate privilege to root and write the implant to the file system. Cisco identified CVE-2023-20273 as the vulnerability exploited to deploy the implant. CVE-2021-1435, previously associated with the exploitation events, is no longer believed to be related to this activity.

Cisco IOS XE Web UI contains a privilege escalation vulnerability in the web user interface that could allow a remote, unauthenticated attacker to create an account with privilege level 15 access. The attacker can then use that account to gain control of the affected device.

HTTP/2 contains a rapid reset vulnerability that allows for a distributed denial-of-service attack (DDoS).

Microsoft Skype for Business contains an unspecified vulnerability that allows for privilege escalation.

Microsoft WordPad contains an unspecified vulnerability that allows for information disclosure.

Adobe Acrobat and Reader contains a use-after-free vulnerability that allows for code execution in the context of the current user.

Cisco IOS and IOS XE contain an out-of-bounds write vulnerability in the Group Encrypted Transport VPN (GET VPN) feature that could allow an authenticated, remote attacker who has administrative control of either a group member or a key server to execute malicious code or cause a device to crash.

Apple iOS and iPadOS contain an unspecified vulnerability that allows for local privilege escalation.

Microsoft Windows Cryptographic Next Generation (CNG) Key Isolation Service contains an unspecified vulnerability that allows an attacker to gain specific limited SYSTEM privileges.

Arm Mali GPU Kernel Driver contains a use-after-free vulnerability that allows a local, non-privileged user to make improper GPU memory processing operations to gain access to already freed memory.

Google Chromium libvpx contains a heap buffer overflow vulnerability in vp8 encoding that allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability could impact web browsers using libvpx, including but not limited to Google Chrome.

Red Hat JBoss RichFaces Framework contains an expression language injection vulnerability via the UserResource resource. A remote, unauthenticated attacker could exploit this vulnerability to execute malicious code using a chain of Java serialized objects via org.ajax4jsf.resource.UserResource$UriData.

Apple iOS, iPadOS, macOS, and Safari WebKit contain an unspecified vulnerability that leads to code execution when processing maliciously crafted web content. This vulnerability could impact HTML parsers that use WebKit, including but not limited to Apple Safari and non-Apple products which rely on WebKit for HTML processing.

Apple iOS, iPadOS, macOS, and watchOS contain an unspecified vulnerability that allows for local privilege escalation.

Apple iOS, iPadOS, macOS, and watchOS contain an improper certificate validation vulnerability that can allow a malicious app to bypass signature validation.

Trend Micro Apex One and Worry-Free Business Security contain an unspecified vulnerability in the third-party anti-virus uninstaller that could allow an attacker to manipulate the module to conduct remote code execution. An attacker must first obtain administrative console access on the target system in order to exploit this vulnerability.

MinIO contains a security feature bypass vulnerability that allows an attacker to use crafted requests to bypass metadata bucket name checking and put an object into any bucket while processing `PostPolicyBucket` to conduct privilege escalation. To carry out this attack, the attacker requires credentials with `arn:aws:s3:::*` permission, as well as enabled Console API access.

Samsung devices with selected Exynos chipsets contain a use-after-free vulnerability that allows malicious memory write and code execution.

Realtek SDK contains an improper input validation vulnerability in the miniigd SOAP service that allows remote attackers to execute malicious code via a crafted NewInternalClient request.

Adobe Acrobat and Reader contains an out-of-bounds write vulnerability that allows for code execution.

Google Chromium WebP contains a heap-based buffer overflow vulnerability that allows a remote attacker to perform an out-of-bounds memory write via a crafted HTML page. This vulnerability can affect applications that use the WebP Codec.

Android Framework contains an unspecified vulnerability that allows for privilege escalation.

Microsoft Streaming Service Proxy contains an unspecified vulnerability that allows for privilege escalation.
