Dell Encryption versions prior to 10.8 and Dell Endpoint Security Suite versions prior to 2.8 contain a privilege escalation vulnerability because of an incomplete fix for CVE-2020-5358. A local malicious user with low privileges could potentially exploit this vulnerability to gain elevated privilege on the affected system with the help of a symbolic link.

The TIBCO Data Virtualization Server component of TIBCO Software Inc.'s TIBCO Data Virtualization and TIBCO Data Virtualization for AWS Marketplace contains a vulnerability that theoretically allows a malicious authenticated user to download any arbitrary file from the affected system. The user must be authenticated and have privileges required to monitor the server in an operational capacity. Affected releases are TIBCO Software Inc.'s TIBCO Data Virtualization: versions 7.0.8 and below, versions 8.0.0, 8.1.0, 8.1.1, and 8.2.0 and TIBCO Data Virtualization for AWS Marketplace: versions 8.2.0 and below.

D-Link DIR-822 Rev.Bx devices with firmware v.202KRb06 and older allow a buffer overflow via long MacAddress data in a /HNAP1/SetClientInfo HNAP protocol message, which is mishandled in /usr/sbin/udhcpd during reading of the /var/servd/LAN-1-udhcpd.conf file.

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. The function parsing the received SNMP request does not verify the input message's requested variables against the capacity of the internal SNMP engine buffer. If the number of variables in the request exceeds the allocated buffer, a memory write out of the buffer boundaries occurs. This write operation provides a possibility to overwrite other variables allocated in the .bss section by the application. Because the sender of the frame is in control of the content that will be written beyond the buffer limits, and there is no strict process memory separation, this issue may allow overwriting of sensitive memory areas of an IoT device.

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP bulk get request response encoding function. The function parsing the received SNMP request does not verify the input message's requested variables against the capacity of the internal SNMP engine buffer. When a bulk get request response is assembled, a stack buffer dedicated for OIDs (with a limited capacity) is allocated in snmp_engine_get_bulk(). When snmp_engine_get_bulk() is populating the stack buffer, an overflow condition may occur due to lack of input length validation. This makes it possible to overwrite stack regions beyond the allocated buffer, including the return address from the function. As a result, the code execution path may be redirected to an address provided in the SNMP bulk get payload. If the target architecture uses common addressing space for program and data memory, it may also be possible to supply code in the SNMP request payload, and redirect the execution path to the remotely injected code, by modifying the function's return address.

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. Functions parsing the OIDs in SNMP requests lack sufficient allocated target-buffer capacity verification when writing parsed OID values. The function snmp_oid_decode_oid() may overwrite memory areas beyond the provided target buffer, when called from snmp_message_decode() upon an SNMP request reception. Because the content of the write operations is externally provided in the SNMP requests, it enables a remote overwrite of an IoT device's memory regions beyond the allocated buffer. This overflow may allow remote overwrite of stack and statically allocated variables memory regions by sending a crafted SNMP request.

Elastic Enterprise Search before 7.9.0 contain a credential exposure flaw in the App Search interface. If a user is given the �developer� role, they will be able to view the administrator API credentials. These credentials could allow the developer user to conduct operations with the same permissions of the App Search administrator.

In Elasticsearch before 7.9.0 and 6.8.12 a field disclosure flaw was found when running a scrolling search with Field Level Security. If a user runs the same query another more privileged user recently ran, the scrolling search can leak fields that should be hidden. This could result in an attacker gaining additional permissions against a restricted index.

Memory access out of buffer boundaries issues was discovered in Contiki-NG 4.4 through 4.5, in the SNMP BER encoder/decoder. The length of provided input/output buffers is insufficiently verified during the encoding and decoding of data. This may lead to out-of-bounds buffer read or write access in BER decoding and encoding functions.
