Improper Access Control

A vulnerability in the distribution list feature of Cisco Webex Meetings could allow an authenticated, remote attacker to modify a distribution list that belongs to another user of their organization. The vulnerability is due to insufficient authorization enforcement for requests to update distribution lists. An attacker could exploit this vulnerability by sending a crafted request to the Webex Meetings interface to modify an existing distribution list. A successful exploit could allow the attacker to modify a distribution list that belongs to a user other than themselves.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.Show less

OpenCTI is an open source platform allowing organizations to manage their cyber threat intelligence knowledge and observables. Prior to version 6.1.9, the regex validation used to prevent Introspection queries can be bypassed by removing the extra whitespace, carriage return, and line feed characters from the query. GraphQL Queries in OpenCTI can be validated using the `secureIntrospectionPlugin`. The regex check in the plkugin can be bypassed by removing the carriage return and line feed characters (`\r\n`). Running a curl command against a local instance of OpenCTI will result in a limited error message. By running the same Introspection query without the `\r\n` characters, the unauthenticated user is able to successfully run a full Introspection query. Bypassing this restriction allows the attacker to gather a wealth of information about the GraphQL endpoint functionality that can be used to perform actions and/or read data without authorization. These queries can also be weaponized to conduct a Denial of Service (DoS) attack if sent repeatedly. Users should upgrade to version 6.1.9 to receive a patch for the issue.Show less

Nextcloud Server is a self hosted personal cloud system. After a user received a share with some files inside being blocked by the files access control, the user would still be able to copy the intermediate folder inside Nextcloud allowing them to afterwards potentially access the blocked files depending on the user access control rules. It is recommended that the Nextcloud Server is upgraded to 27.1.9, 28.0.5 or 29.0.0 and Nextcloud Enterprise Server is upgraded to 21.0.9.18, 22.2.10.23, 23.0.12.18, 24.0.12.14, 25.0.13.9, 26.0.13.3, 27.1.9, 28.0.5 or 29.0.0.Show less

Nextcloud Mail is the mail app for Nextcloud, a self-hosted productivity platform. The Nextcloud mail app incorrectly allowed attaching shared files without download permissions as attachments. This allowed users to send them the files to themselves and then downloading it from their mail clients. It is recommended that the Nextcloud Mail is upgraded to 2.2.10, 3.6.2 or 3.7.2.Show less

CRMEB <=5.4.0 is vulnerable to Incorrect Access Control. Users can bypass the front-end restriction of only being able to claim coupons once by capturing packets and sending a large number of data packets for coupon collection, achieving unlimited coupon collection.Show less

A vulnerability in the payload inspection for Ethernet Industrial Protocol (ENIP) traffic for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured rules for ENIP traffic. This vulnerability is due to incomplete processing during deep packet inspection for ENIP packets. An attacker could exploit this vulnerability by sending a crafted ENIP packet to the targeted interface. A successful exploit could allow the attacker to bypass configured access control and intrusion policies that should trigger and drop for the ENIP packet.Show less

A vulnerability in the implementation of the Simple Network Management Protocol (SNMP) IPv4 access control list (ACL) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to perform SNMP polling of an affected device, even if it is configured to deny SNMP traffic.&nbsp; This vulnerability exists because Cisco IOS Software and Cisco IOS XE Software do not support extended IPv4 ACLs for SNMP, but they do allow administrators to configure extended named IPv4 ACLs that are attached to the SNMP server configuration without a warning message. This can result in no ACL being applied to the SNMP listening process. An attacker could exploit this vulnerability by performing SNMP polling of an affected device. A successful exploit could allow the attacker to perform SNMP operations that should be denied. The attacker has no control of the SNMP ACL configuration and would still need a valid SNMP version 2c (SNMPv2c) community string or SNMP version 3 (SNMPv3) user credentials. SNMP with IPv6 ACL configurations is not affected. For more information, see the section of this advisory.Show less

An improper access control vulnerability exists in janeczku/calibre-web. The affected version allows users without public shelf permissions to create public shelves. The vulnerability is due to the `create_shelf` method in `shelf.py` not verifying if the user has the necessary permissions to create a public shelf. This issue can lead to unauthorized actions being performed by users.Show less
