Security Vulnerabilities, CVEs, Published In 2022 (Denial of service)

TP-Link TL-WR902AC devices through V3 0.9.1 allow remote authenticated attackers to execute arbitrary code or cause a Denial of Service (DoS) by uploading a crafted firmware update because the signature check is inadequate.

An issue was discovered in the Linux kernel 5.10.x before 5.10.155. A use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can be skipped. An attack can occur in some situations by forking a process and then quickly terminating it. NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of io_sqpoll_wait_sq.

Brave Browser before 1.43.88 allowed a remote attacker to cause a denial of service in private and guest windows via a crafted HTML file that mentions an ipfs:// or ipns:// URL. This is caused by an incomplete fix for CVE-2022-47932 and CVE-2022-47934.

Brave Browser before 1.42.51 allowed a remote attacker to cause a denial of service via a crafted HTML file that references the IPFS scheme. This vulnerability is caused by an uncaught exception in the function ipfs::OnBeforeURLRequest_IPFSRedirectWork() in ipfs_redirect_network_delegate_helper.cc.

Brave Browser before 1.43.34 allowed a remote attacker to cause a denial of service via a crafted HTML file that mentions an ipfs:// or ipns:// URL. This vulnerability is caused by an incomplete fix for CVE-2022-47933.

An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.19. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that causes a url_canonize2 heap-based buffer over-read because of an off-by-one error.

An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.20. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that leads to a failure of the libsofia-sip-ua/tport/tport.c self assertion.

An issue was discovered in drachtio-server before 0.8.20. It allows remote attackers to cause a denial of service (daemon crash) via a long message in a TCP request that leads to std::length_error.

An issue in the firmware update process of TP-Link TL-WR941ND V2/V3 up to 3.13.9 and TL-WR941ND V4 up to 3.12.8 allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via uploading a crafted firmware image.

An issue in the firmware update process of TP-Link TL-WA7510N v1 v3.12.6 and earlier allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via uploading a crafted firmware image.

An exploitable firmware modification vulnerability was discovered on TP-Link TL-WR743ND V1. An attacker can conduct a MITM (Man-in-the-Middle) attack to modify the user-uploaded firmware image and bypass the CRC check, allowing attackers to execute arbitrary code or cause a Denial of Service (DoS). This affects v3.12.20 and earlier.

TP-Link TL-WR740N V1 and V2 v3.12.4 and earlier allows authenticated attackers to execute arbitrary code or cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

TP-Link TL-WR1043ND V1 3.13.15 and earlier allows authenticated attackers to execute arbitrary code or cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

An exploitable firmware modification vulnerability was discovered on the Netgear XWN5001 Powerline 500 WiFi Access Point. An attacker can conduct a MITM (Man-in-the-Middle) attack to modify the user-uploaded firmware image and bypass the CRC check, allowing attackers to execute arbitrary code or cause a Denial of Service (DoS). This affects v0.4.1.1 and earlier.

An exploitable firmware modification vulnerability was discovered on the Netgear WNR2000v1 router. An attacker can conduct a MITM (Man-in-the-Middle) attack to modify the user-uploaded firmware image and bypass the CRC check, allowing attackers to execute arbitrary code or cause a Denial of Service (DoS). This affects v1.2.3.7 and earlier.

An issue in Netgear WNR2000 v1 1.2.3.7 and earlier allows authenticated attackers to cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

Mastodon through 4.0.2 allows attackers to cause a denial of service (large Sidekiq pull queue) by creating bot accounts that follow attacker-controlled accounts on certain other servers associated with a wildcard DNS A record, such that there is uncontrolled recursion of attacker-generated messages.

A vulnerability has been identified in SCALANCE X204RNA (HSR) (All versions < V3.2.7), SCALANCE X204RNA (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (HSR) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP/HSR) (All versions < V3.2.7). Specially crafted PROFINET DCP packets could cause a denial of service condition of affected products.

A vulnerability has been identified in SCALANCE X204RNA (HSR) (All versions < V3.2.7), SCALANCE X204RNA (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (HSR) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP) (All versions < V3.2.7), SCALANCE X204RNA EEC (PRP/HSR) (All versions < V3.2.7).

JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). The `parse` method of the JSON5 library before and including versions 1.0.1 and 2.2.1 does not restrict parsing of keys named `__proto__`, allowing specially crafted strings to pollute the prototype of the resulting object. This vulnerability pollutes the prototype of the object returned by `JSON5.parse` and not the global Object prototype, which is the commonly understood definition of Prototype Pollution. However, polluting the prototype of a single object can have significant security impact for an application if the object is later used in trusted operations. This vulnerability could allow an attacker to set arbitrary and unexpected keys on the object returned from `JSON5.parse`. The actual impact will depend on how applications utilize the returned object and how they filter unwanted keys, but could include denial of service, cross-site scripting, elevation of privilege, and in extreme cases, remote code execution. `JSON5.parse` should restrict parsing of `__proto__` keys when parsing JSON strings to objects. As a point of reference, the `JSON.parse` method included in JavaScript ignores `__proto__` keys. Simply changing `JSON5.parse` to `JSON.parse` in the examples above mitigates this vulnerability. This vulnerability is patched in json5 versions 1.0.2, 2.2.2, and later.
