Improper Input Validation

A vulnerability in the 802.11 association frame validation of Cisco Catalyst 9100 Series Access Points (APs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of certain parameters within association request frames received by the AP. An attacker could exploit this vulnerability by sending a crafted 802.11 association request to a nearby device. An exploit could allow the attacker to unexpectedly reload the device, resulting in a DoS condition.Show less

A vulnerability in the CLI of stand-alone Cisco IOS XE SD-WAN Software and Cisco SD-WAN Software could allow an authenticated, local attacker to delete arbitrary files from the file system of an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary file path information when using commands in the CLI of an affected device. A successful exploit could allow the attacker to delete arbitrary files from the file system of the affected device.Show less

Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.Show less

sflow decode package does not employ sufficient packet sanitisation which can lead to a denial of service attack. Attackers can craft malformed packets causing the process to consume large amounts of memory resulting in a denial of service.Show less

Discourse is an open source discussion platform. Starting with version 2.9.0.beta5 and prior to version 2.9.0.beta10, an incomplete quote can generate a JavaScript error which will crash the current page in the browser in some cases. Version 2.9.0.beta10 added a fix and tests to ensure incomplete quotes won't break the app. As a workaround, the quote can be fixed via the rails console.Show less

Discourse is an open source discussion platform. In versions prior to 2.8.9 on the `stable` branch and prior to 2.9.0.beta10 on the `beta` and `tests-passed` branches, a malicious actor can add large payloads of text into the Location and Website fields of a user profile, which causes issues for other users when loading that profile. A fix to limit the length of user input for these fields is included in version 2.8.9 on the `stable` branch and version 2.9.0.beta10 on the `beta` and `tests-passed` branches. There are no known workarounds.Show less

isolated-vm is a library for nodejs which gives the user access to v8's Isolate interface. In versions 4.3.6 and prior, if the untrusted v8 cached data is passed to the API through CachedDataOptions, attackers can bypass the sandbox and run arbitrary code in the nodejs process. Version 4.3.7 changes the documentation to warn users that they should not accept `cachedData` payloads from a user.Show less

QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process.Show less

In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.Show less

Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Starting with version 17.1.0-rc.1, improperly formed beacon events can disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This is patched in matrix-js-sdk v19.7.0. Redacting applicable events, waiting for the sync processor to store data, and restarting the client are possible workarounds. Alternatively, redacting the applicable events and clearing all storage will fix the further perceived issues. Downgrading to an unaffected version, noting that such a version may be subject to other vulnerabilities, will additionally resolve the issue.Show less

Insufficient validation of untrusted input in DevTools in Google Chrome on Chrome OS prior to 105.0.5195.125 allowed an attacker who convinced a user to install a malicious extension to bypass navigation restrictions via a crafted HTML page. (Chromium security severity: High)Show less

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. An SMM memory corruption vulnerability in the FvbServicesRuntimeDxe driver allows an attacker to write fixed or predictable data to SMRAM. Exploiting this issue could lead to escalating privileges to SMM.Show less

This issue was addressed with improved checks. This issue is fixed in Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, macOS Monterey 12.5. Processing a maliciously crafted AppleScript binary may result in unexpected termination or disclosure of process memory.Show less

An issue in the handling of environment variables was addressed with improved validation. This issue is fixed in Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, macOS Monterey 12.5. An app may be able to modify protected parts of the file system.Show less

An improper access control vulnerability exists in Rocket.Chat <v5, <v4.8.2 and <v4.7.5 due to input data in the getUsersOfRoom Meteor server method is not type validated, so that MongoDB query operator objects are accepted by the server, so that instead of a matching rid String a$regex query can be executed, bypassing the room access permission check for every but the first matching room.Show less
