CVE-2021-43068 1 Fortinet 1 Fortiauthenticator 2021-12-10 5.5 MEDIUM 8.1 HIGH
A improper authentication in Fortinet FortiAuthenticator version 6.4.0 allows user to bypass the second factor of authentication via a RADIUS login portal.
CVE-2021-43544 2 Google, Mozilla 2 Android, Firefox 2021-12-10 4.3 MEDIUM 6.1 MEDIUM
When receiving a URL through a SEND intent, Firefox would have searched for the text, but subsequent usages of the address bar might have caused the URL to load unintentionally, which could lead to XSS and spoofing attacks. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 95.
CVE-2021-40288 1 Tp-link 2 Archer Ax10, Archer Ax10 Firmware 2021-12-10 7.8 HIGH 7.5 HIGH
A denial-of-service attack in WPA2, and WPA3-SAE authentication methods in TP-Link AX10v1 before V1_211014, allows a remote unauthenticated attacker to disconnect an already connected wireless client via sending with a wireless adapter specific spoofed authentication frames
CVE-2021-28709 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2021-12-09 6.9 MEDIUM 7.8 HIGH
issues with partially successful P2M updates on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). In some cases the hypervisor carries out the requests by splitting them into smaller chunks. Error handling in certain PoD cases has been insufficient in that in particular partial success of some operations was not properly accounted for. There are two code paths affected - page removal (CVE-2021-28705) and insertion of new pages (CVE-2021-28709). (We provide one patch which combines the fix to both issues.)
CVE-2021-43697 1 Workerman-thinkphp-redis Project 1 Workerman-thinkphp-redis 2021-12-09 4.3 MEDIUM 6.1 MEDIUM
Workerman-ThinkPHP-Redis (last update Mar 16, 2018) is affected by a Cross Site Scripting (XSS) vulnerability. In file Controller.class.php, the exit function will terminate the script and print the message to the user. The message will contain $_GET{C('VAR_JSONP_HANDLER')] then there is a XSS vulnerability.
CVE-2020-29487 1 Xen 1 Xapi 2021-12-09 7.8 HIGH 7.5 HIGH
An issue was discovered in Xen XAPI before 2020-12-15. Certain xenstore keys provide feedback from the guest, and are therefore watched by toolstack. Specifically, keys are watched by xenopsd, and data are forwarded via RPC through message-switch to xapi. The watching logic in xenopsd sends one RPC update containing all data, any time any single xenstore key is updated, and therefore has O(N^2) time complexity. Furthermore, message-switch retains recent (currently 128) RPC messages for diagnostic purposes, yielding O(M*N) space complexity. The quantity of memory a single guest can monopolise is bounded by xenstored quota, but the quota is fairly large. It is believed to be in excess of 1G per malicious guest. In practice, this manifests as a host denial of service, either through message-switch thrashing against swap, or OOMing entirely, depending on dom0's configuration. (There are no quotas in xenopsd to limit the quantity of keys that result in RPC traffic.) A buggy or malicious guest can cause unreasonable memory usage in dom0, resulting in a host denial of service. All versions of XAPI are vulnerable. Systems that are not using the XAPI toolstack are not vulnerable.
CVE-2020-29570 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2021-12-09 4.9 MEDIUM 6.2 MEDIUM
An issue was discovered in Xen through 4.14.x. Recording of the per-vCPU control block mapping maintained by Xen and that of pointers into the control block is reversed. The consumer assumes, seeing the former initialized, that the latter are also ready for use. Malicious or buggy guest kernels can mount a Denial of Service (DoS) attack affecting the entire system.
CVE-2020-29566 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2021-12-09 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in Xen through 4.14.x. When they require assistance from the device model, x86 HVM guests must be temporarily de-scheduled. The device model will signal Xen when it has completed its operation, via an event channel, so that the relevant vCPU is rescheduled. If the device model were to signal Xen without having actually completed the operation, the de-schedule / re-schedule cycle would repeat. If, in addition, Xen is resignalled very quickly, the re-schedule may occur before the de-schedule was fully complete, triggering a shortcut. This potentially repeating process uses ordinary recursive function calls, and thus could result in a stack overflow. A malicious or buggy stubdomain serving a HVM guest can cause Xen to crash, resulting in a Denial of Service (DoS) to the entire host. Only x86 systems are affected. Arm systems are not affected. Only x86 stubdomains serving HVM guests can exploit the vulnerability.
CVE-2020-29571 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2021-12-09 4.9 MEDIUM 6.2 MEDIUM
An issue was discovered in Xen through 4.14.x. A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered reads, and may hence end up de-referencing a NULL pointer. Malicious or buggy guest kernels can mount a Denial of Service (DoS) attack affecting the entire system. Only Arm systems may be vulnerable. Whether a system is vulnerable depends on the specific CPU. x86 systems are not vulnerable.
CVE-2020-29567 2 Fedoraproject, Xen 2 Fedora, Xen 2021-12-09 4.9 MEDIUM 6.2 MEDIUM
An issue was discovered in Xen 4.14.x. When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checked, the checking CPU may send an interrupt to itself, in the expectation that this IRQ will be delivered only after the condition preventing the cleanup has cleared. For two specific IRQ vectors, this expectation was violated, resulting in a continuous stream of self-interrupts, which renders the CPU effectively unusable. A domain with a passed through PCI device can cause lockup of a physical CPU, resulting in a Denial of Service (DoS) to the entire host. Only x86 systems are vulnerable. Arm systems are not vulnerable. Only guests with physical PCI devices passed through to them can exploit the vulnerability.
CVE-2020-29486 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2021-12-09 4.9 MEDIUM 6.0 MEDIUM
An issue was discovered in Xen through 4.14.x. Nodes in xenstore have an ownership. In oxenstored, a owner could give a node away. However, node ownership has quota implications. Any guest can run another guest out of quota, or create an unbounded number of nodes owned by dom0, thus running xenstored out of memory A malicious guest administrator can cause a denial of service against a specific guest or against the whole host. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
