CVE-2021-21410 1 Contiki-ng 1 Contiki-ng 2024-11-21 8.2 High
Contiki-NG is an open-source, cross-platform operating system for Next-Generation IoT devices. An out-of-bounds read can be triggered by 6LoWPAN packets sent to devices running Contiki-NG 4.6 and prior. The IPv6 header decompression function (<code>uncompress_hdr_iphc</code>) does not perform proper boundary checks when reading from the packet buffer. Hence, it is possible to construct a compressed 6LoWPAN packet that will read more bytes than what is available from the packet buffer. As of time of publication, there is not a release with a patch available. Users can apply the patch for this vulnerability out-of-band as a workaround.
CVE-2021-21368 1 Msgpack5 Project 1 Msgpack5 2024-11-21 6.7 Medium
msgpack5 is a msgpack v5 implementation for node.js and the browser. In msgpack5 before versions 3.6.1, 4.5.1, and 5.2.1 there is a "Prototype Poisoning" vulnerability. When msgpack5 decodes a map containing a key "__proto__", it assigns the decoded value to __proto__. Object.prototype.__proto__ is an accessor property for the receiver's prototype. If the value corresponding to the key __proto__ decodes to an object or null, msgpack5 sets the decoded object's prototype to that value. An attacker who can submit crafted MessagePack data to a service can use this to produce values that appear to be of other types; may have unexpected prototype properties and methods (for example length, numeric properties, and push et al if __proto__'s value decodes to an Array); and/or may throw unexpected exceptions when used (for example if the __proto__ value decodes to a Map or Date). Other unexpected behavior might be produced for other types. There is no effect on the global prototype. This "prototype poisoning" is sort of a very limited inversion of a prototype pollution attack. Only the decoded value's prototype is affected, and it can only be set to msgpack5 values (though if the victim makes use of custom codecs, anything could be a msgpack5 value). We have not found a way to escalate this to true prototype pollution (absent other bugs in the consumer's code). This has been fixed in msgpack5 version 3.6.1, 4.5.1, and 5.2.1. See the referenced GitHub Security Advisory for an example and more details.
CVE-2021-21366 2 Debian, Xmldom Project 2 Debian Linux, Xmldom 2024-11-21 4.3 Medium
xmldom is a pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. xmldom versions 0.4.0 and older do not correctly preserve system identifiers, FPIs or namespaces when repeatedly parsing and serializing maliciously crafted documents. This may lead to unexpected syntactic changes during XML processing in some downstream applications. This is fixed in version 0.5.0. As a workaround downstream applications can validate the input and reject the maliciously crafted documents.
CVE-2021-21317 1 Uap-core Project 1 Uap-core 2024-11-21 5.3 Medium
uap-core in an open-source npm package which contains the core of BrowserScope's original user agent string parser. In uap-core before version 0.11.0, some regexes are vulnerable to regular expression denial of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings. This is fixed in version 0.11.0. Downstream packages such as uap-python, uap-ruby etc which depend upon uap-core follow different version schemes.
CVE-2021-21309 2 Redhat, Redislabs 2 Acm, Redis 2024-11-21 5.4 Medium
Redis is an open-source, in-memory database that persists on disk. In affected versions of Redis an integer overflow bug in 32-bit Redis version 4.0 or newer could be exploited to corrupt the heap and potentially result with remote code execution. Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption. We believe this could in certain conditions be exploited for remote code execution. By default, authenticated Redis users have access to all configuration parameters and can therefore use the “CONFIG SET proto-max-bulk-len” to change the safe default, making the system vulnerable. **This problem only affects 32-bit Redis (on a 32-bit system, or as a 32-bit executable running on a 64-bit system).** The problem is fixed in version 6.2, and the fix is back ported to 6.0.11 and 5.0.11. Make sure you use one of these versions if you are running 32-bit Redis. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent clients from directly executing `CONFIG SET`: Using Redis 6.0 or newer, ACL configuration can be used to block the command. Using older versions, the `rename-command` configuration directive can be used to rename the command to a random string unknown to users, rendering it inaccessible. Please note that this workaround may have an additional impact on users or operational systems that expect `CONFIG SET` to behave in certain ways.
CVE-2021-21304 1 Dynamoosejs 1 Dynamoose 2024-11-21 7.2 High
Dynamoose is an open-source modeling tool for Amazon's DynamoDB. In Dynamoose from version 2.0.0 and before version 2.7.0 there was a prototype pollution vulnerability in the internal utility method "lib/utils/object/set.ts". This method is used throughout the codebase for various operations throughout Dynamoose. We have not seen any evidence of this vulnerability being exploited. There is no evidence this vulnerability impacts versions 1.x.x since the vulnerable method was added as part of the v2 rewrite. This vulnerability also impacts v2.x.x beta/alpha versions. Version 2.7.0 includes a patch for this vulnerability.
CVE-2021-21302 1 Prestashop 1 Prestashop 2024-11-21 6.8 Medium
PrestaShop is a fully scalable open source e-commerce solution. In PrestaShop before version 1.7.2 there is a CSV Injection vulnerability possible by using shop search keywords via the admin panel. The problem is fixed in 1.7.7.2
CVE-2021-21297 1 Nodered 1 Node-red 2024-11-21 7.7 High
Node-Red is a low-code programming for event-driven applications built using nodejs. Node-RED 1.2.7 and earlier contains a Prototype Pollution vulnerability in the admin API. A badly formed request can modify the prototype of the default JavaScript Object with the potential to affect the default behaviour of the Node-RED runtime. The vulnerability is patched in the 1.2.8 release. A workaround is to ensure only authorized users are able to access the editor url.
CVE-2021-21282 1 Contiki-ng 1 Contiki-ng 2024-11-21 8.6 High
Contiki-NG is an open-source, cross-platform operating system for internet of things devices. In versions prior to 4.5, buffer overflow can be triggered by an input packet when using either of Contiki-NG's two RPL implementations in source-routing mode. The problem has been patched in Contiki-NG 4.5. Users can apply the patch for this vulnerability out-of-band as a workaround.
CVE-2021-21281 1 Contiki-ng 1 Contiki-ng 2024-11-21 7 High
Contiki-NG is an open-source, cross-platform operating system for internet of things devices. A buffer overflow vulnerability exists in Contiki-NG versions prior to 4.6. After establishing a TCP socket using the tcp-socket library, it is possible for the remote end to send a packet with a data offset that is unvalidated. The problem has been patched in Contiki-NG 4.6. Users can apply the patch for this vulnerability out-of-band as a workaround.
