CVSS: 6.0EPSS: 0%CPEs: 7EXPL: 0CVE-2024-39539 – Junos OS: MX Series: Continuous subscriber logins will lead to a memory leak and eventually an FPC crash
https://notcve.org/view.php?id=CVE-2024-39539
A Missing Release of Memory after Effective Lifetime vulnerability in Juniper Networks Junos OS on MX Series allows an unauthenticated adjacent attacker to cause a Denial-of-Service (DoS). In a subscriber management scenario continuous subscriber logins will trigger a memory leak and eventually lead to an FPC crash and restart. This issue affects Junos OS on MX Series: * All version before 21.2R3-S6, * 21.4 versions before 21.4R3-S6, * 22.1 versions before 22.1R3-S5, * 22.2 versions before 22.2R3-S3, * 22.3 versions before 22.3R3-S2, * 22.4 versions before 22.4R3, * 23.2 versions before 23.2R2. • https://supportportal.juniper.net/JSA82999 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 6.0EPSS: 0%CPEs: 13EXPL: 0CVE-2024-39536 – Junos OS and Junos OS Evolved: Flaps of BFD sessions with authentication cause a ppmd memory leak
https://notcve.org/view.php?id=CVE-2024-39536
A Missing Release of Memory after Effective Lifetime vulnerability in the Periodic Packet Management Daemon (ppmd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a Denial-of-Service (DoS). When a BFD session configured with authentication flaps, ppmd memory can leak. Whether the leak happens depends on a race condition which is outside the attackers control. This issue only affects BFD operating in distributed aka delegated (which is the default behavior) or inline mode. Whether the leak occurs can be monitored with the following CLI command: > show ppm request-queue FPC Pending-request fpc0 2 request-total-pending: 2 where a continuously increasing number of pending requests is indicative of the leak. This issue affects: Junos OS: * All versions before 21.2R3-S8, * 21.4 versions before 21.4R3-S7, * 22.1 versions before 22.1R3-S4, * 22.2 versions before 22.2R3-S4, * 22.3 versions before 22.3R3, * 22.4 versions before 22.4R2-S2, 22.4R3. Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4-EVO versions before 21.4R3-S7-EVO, * 22.2-EVO versions before 22.2R3-S4-EVO, * 22.3-EVO versions before 22.3R3-EVO, * 22.4-EVO versions before 22.4R3-EVO. • https://supportportal.juniper.net/JSA82996 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 6.9EPSS: 0%CPEs: 7EXPL: 0CVE-2024-39533 – Junos OS: QFX5000 Series and EX4600 Series: Output firewall filter is not applied if certain match criteria are used
https://notcve.org/view.php?id=CVE-2024-39533
An Unimplemented or Unsupported Feature in the UI vulnerability in Juniper Networks Junos OS on QFX5000 Series and EX4600 Series allows an unauthenticated, network-based attacker to cause a minor integrity impact to downstream networks.If one or more of the following match conditions ip-source-address ip-destination-address arp-type which are not supported for this type of filter, are used in an ethernet switching filter, and then this filter is applied as an output filter, the configuration can be committed but the filter will not be in effect. This issue affects Junos OS on QFX5000 Series and EX4600 Series: * All version before 21.2R3-S7, * 21.4 versions before 21.4R3-S6, * 22.1 versions before 22.1R3-S5, * 22.2 versions before 22.2R3-S3, * 22.3 versions before 22.3R3-S2, * 22.4 versions before 22.4R3, * 23.2 versions before 23.2R2. Please note that the implemented fix ensures these unsupported match conditions cannot be committed anymore. • https://supportportal.juniper.net/JSA82993 • CWE-447: Unimplemented or Unsupported Feature in UI •
CVSS: 6.3EPSS: 0%CPEs: 11EXPL: 0CVE-2024-39532 – Junos OS and Junos OS Evolved: Confidential information in logs can be accessed by another user
https://notcve.org/view.php?id=CVE-2024-39532
An Insertion of Sensitive Information into Log File vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows a local, authenticated attacker with high privileges to access sensitive information. When another user performs a specific operation, sensitive information is stored as plain text in a specific log file, so that a high-privileged attacker has access to this information. This issue affects: Junos OS: * All versions before 22.1R2-S2, * 22.1R3 and later versions, * 22.2 versions before 22.2R2-S1, 22.2R3, * 22.3 versions before 22.3R1-S2, 22.3R2; Junos OS Evolved: * All versions before before 22.1R3-EVO, * 22.2-EVO versions before 22.2R2-S1-EVO, 22.2R3-EVO, * 22.3-EVO versions before 22.3R1-S1-EVO, 22.3R2-EVO. • https://supportportal.juniper.net/JSA82992 • CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 8.7EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39530 – Junos OS: Attempting to access specific sensors on platforms not supporting these will lead to a chassisd crash
https://notcve.org/view.php?id=CVE-2024-39530
An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis management daemon (chassisd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). If an attempt is made to access specific sensors on platforms not supporting these sensors, either via GRPC or netconf, chassisd will crash and restart leading to a restart of all FPCs and thereby a complete outage. This issue affects Junos OS: * 21.4 versions from 21.4R3 before 21.4R3-S5, * 22.1 versions from 22.1R3 before 22.1R3-S4, * 22.2 versions from 22.2R2 before 22.2R3, * 22.3 versions from 22.3R1 before 22.3R2-S2, 22.3R3, * 22.4 versions from 22.4R1 before 22.4R2. This issue does not affect Junos OS versions earlier than 21.4. • https://supportportal.juniper.net/JSA82989 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
