kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members

The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.

Easy!Appointments 1.3.0 has a Guessable CAPTCHA issue.

The report-viewing feature in Pearson VUE Certiport Console 8 and IQSystem 7 before 2018-06-26 mishandles child processes and consequently launches Internet Explorer or Microsoft Edge as Administrator, which allows local users to gain privileges.

Hycus CMS 1.0.4 allows Authentication Bypass via "'=' 'OR'" credentials.

kernel: kvm: nVMX: missing privilege check allows privilege escalation in nested virtualization

In arch/x86/kvm/vmx.c in the Linux kernel before 4.17.2, when nested virtualization is used, local attackers could cause L1 KVM guests to VMEXIT, potentially allowing privilege escalations and denial of service attacks due to lack of checking of CPL.

xen: libxl fails to honour readonly flag on HVM emulated SCSI disks

An issue was discovered in Xen 4.7 through 4.10.x. libxl fails to pass the readonly flag to qemu when setting up a SCSI disk, due to what was probably an erroneous merge conflict resolution. Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images. Only emulated SCSI disks (specified as "sd" in the libxl disk configuration, or an equivalent) are affected. IDE disks ("hd") are not affected (because attempts to make them readonly are rejected). Additionally, CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected; they are always read only. Only systems using qemu-xen (rather than qemu-xen-traditional) as the device model version are vulnerable. Only systems using libxl or libxl-based toolstacks are vulnerable. (This includes xl, and libvirt with the libxl driver.) The vulnerability is present in Xen versions 4.7 and later. (In earlier versions, provided that the patch for XSA-142 has been applied, attempts to create read only disks are rejected.) If the host and guest together usually support PVHVM, the issue is exploitable only if the malicious guest administrator has control of the guest kernel or guest kernel command line.

Adobe Connect versions 9.7.5 and earlier have an Authentication Bypass vulnerability. Successful exploitation could lead to session hijacking.

The SV3C HD Camera (L-SERIES V2.3.4.2103-S50-NTD-B20170508B and V2.3.4.2103-S50-NTD-B20170823B) is affected by an improper authentication vulnerability that allows requests to be made to back-end CGI scripts without a valid session. This vulnerability could be used to read and modify the configuration. The vulnerability affects all versions.

SV3C L-SERIES HD CAMERA V2.3.4.2103-S50-NTD-B20170508B devices improperly identifies users only by the authentication level sent in the cookies, which allow remote attackers to bypass authentication and gain administrator access by setting the authLevel cookie to 255.

An issue was discovered in phpMyAdmin 4.8.x before 4.8.2, in which an attacker can include (view and potentially execute) files on the server. The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages. An attacker must be authenticated, except in the "$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the login requirement and runs the vulnerable code without any authentication).

On TP-Link TL-WR841N v13 00000001 0.9.1 4.16 v0001.0 Build 171019 Rel.55346n devices, all actions in the web interface are affected by bypass of authentication via an HTTP request.

When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use a password file for authentication, any malformed data in the password file will be treated as valid. This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who have only used the mosquitto_passwd utility to create and modify their password files are unaffected by this vulnerability.

In Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) when a client publishes a retained message to a topic, then has its access to that topic revoked, the retained message will still be published to clients that subscribe to that topic in the future. In some applications this may result in clients being able cause effects that would otherwise not be allowed.

JDK: privilege escalation via insufficiently restricted access to Attach API

In Eclipse OpenJ9 version 0.8, users other than the process owner may be able to use Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations, which includes the ability to execute untrusted native code. Attach API is enabled by default on Windows, Linux and AIX JVMs and can be disabled using the command line option -Dcom.ibm.tools.attach.enable=no.

jetty: HttpSessions access/hijack in the FileSystem's storage for the FileSessionDataStore.

In Eclipse Jetty versions 9.4.0 through 9.4.8, when using the optional Jetty provided FileSessionDataStore for persistent storage of HttpSession details, it is possible for a malicious user to access/hijack other HttpSessions and even delete unmatched HttpSessions present in the FileSystem's storage for the FileSessionDataStore.

Authentication bypass in sibling check

A improper authentication using the HOST header in SUSE Linux SMT allows remote attackers to spoof a sibling server. Affected releases are SUSE Linux SMT: versions prior to 3.0.37.

delete package via link exploit in open buildservice

Authorized users of the openbuildservice before 2.9.4 could delete packages by using a malicious request against projects having the OBS:InitializeDevelPackage attribute, a similar issue to CVE-2018-7689.

openbuildservice allowed deleting packages via project links

openSUSE openbuildservice before 9.2.4 allowed authenticated users to delete packages on specific projects with project links.

Intelbras NPLUG 1.0.0.14 wireless repeater devices have a critical vulnerability that allows an attacker to authenticate in the web interface just by using "admin:" as the name of a cookie.

An issue was discovered in the com.dropbox.android application 98.2.2 for Android. The Passcode feature allows authentication bypass via runtime manipulation that forces a certain method's return value to true. In other words, an attacker could authenticate with an arbitrary passcode. NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes Android devices on which rooting has occurred
