Icinga Icinga Web2 2.0.0 through 2.6.4, 2.7.4 and 2.8.2 has a Directory Traversal vulnerability which allows an attacker to access arbitrary files that are readable by the process running Icinga Web 2. This issue is fixed in Icinga Web 2 in v2.6.4, v2.7.4 and v2.8.2.

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.

A command injection vulnerability exists in EdgeSwitch firmware <v1.9.0 that allowed an authenticated read-only user to execute arbitrary shell commands over the HTTP interface, allowing them to escalate privileges.

Use of Hard-coded Credentials in temi Robox OS prior to 120, temi Android app up to 1.3.7931 allows remote attackers to listen in on any ongoing calls between temi robots and their users if they can brute-force/guess a six-digit value via unspecified vectors.

A code injection in Nextcloud Desktop Client 2.6.4 allowed to load arbitrary code when placing a malicious OpenSSL config into a fixed directory.

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.

In etcd before versions 3.3.23 and 3.4.10, certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).

Aerospike Community Edition 4.9.0.5 allows for unauthenticated submission and execution of user-defined functions (UDFs), written in Lua, as part of a database query. It attempts to restrict code execution by disabling os.execute() calls, but this is insufficient. Anyone with network access can use a crafted UDF to execute arbitrary OS commands on all nodes of the cluster at the permission level of the user running the Aerospike service.
