An issue was discovered in Xen through 4.11.x. The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably not to lock up the core. As a result, it must only be available to fully trusted guests. Unfortunately, in the case that vPMU is disabled, all value checking was skipped, allowing the guest to choose any MSR_DEBUGCTL setting it likes. A malicious or buggy guest administrator (on Intel x86 HVM or PVH) can lock up the entire host, causing a Denial of Service.
An issue was discovered in Xen through 4.11.x. ARM never properly implemented grant table v2, either in the hypervisor or in Linux. Unfortunately, an ARM guest can still request v2 grant tables; they will simply not be properly set up, resulting in subsequent grant-related hypercalls hitting BUG() checks. An unprivileged guest can cause a BUG() check in the hypervisor, resulting in a denial-of-service (crash).
An issue was discovered in Xen through 4.11.x. The logic in oxenstored for handling writes depended on the order of evaluation of expressions making up a tuple. As indicated in section 7.7.3 "Operations on data structures" of the OCaml manual, the order of evaluation of subexpressions is not specified. In practice, different implementations behave differently. Thus, oxenstored may not enforce the configured quota-maxentity. This allows a malicious or buggy guest to write as many xenstore entries as it wishes, causing unbounded memory usage in oxenstored. This can lead to a system-wide DoS.
IBM Security Access Manager for Enterprise Single Sign-On 8.2.2 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic. IBM X-Force ID: 134913.
An authenticated attacker can execute arbitrary code using command ejection in Eltex ESP-200 firmware version 1.2.0.
An authenticated attacker with low privileges can extract password hash information for all users in Eltex ESP-200 firmware version 1.2.0.
An authenticated attacker with low privileges can activate high privileged user and use it to expand attack surface in Eltex ESP-200 firmware version 1.2.0.
An authenticated attacker with low privileges can use insecure sudo configuration to expand attack surface in Eltex ESP-200 firmware version 1.2.0.
An attacker without authentication can login with default credentials for privileged users in Eltex ESP-200 firmware version 1.2.0.
Usage of SSLv2 and SSLv3 leads to transmitted data decryption in Kraftway 24F2XG Router firmware 22.214.171.1248.
Router Default Credentials in Kraftway 24F2XG Router firmware version 126.96.36.1998 allow remote attackers to get privileged access to the router.
Denial of service via crafting malicious link and sending it to a privileged user can cause Denial of Service in Kraftway 24F2XG Router firmware version 188.8.131.528.
An attacker with low privileges can cause denial of service in Kraftway 24F2XG Router firmware version 184.108.40.2068.
A Buffer Overflow exploited through web interface by remote attacker can cause remote code execution in Kraftway 24F2XG Router firmware 220.127.116.118.
A Buffer Overflow exploited through web interface by remote attacker can cause denial of service in Kraftway 24F2XG Router firmware 18.104.22.1688.
A privilege escalation detected in flintcms versions <= 1.1.9 allows account takeover due to blind MongoDB injection in password reset.
A code injection in cryo 0.0.6 allows an attacker to arbitrarily execute code due to insecure implementation of deserialization.
A command injection in git-dummy-commit v1.3.0 allows os level commands to be executed due to an unescaped parameter.
A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts.
The svpn and policyserver components of the F5 BIG-IP APM client prior to version 22.214.171.124 for Linux and macOS runs as a privileged process and can allow an unprivileged user to get ownership of files owned by root on the local client host. A malicious local unprivileged user may gain knowledge of sensitive information, manipulate certain data, or assume super-user privileges on the local client host.
