CVSS: 8.7EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39542 – Junos OS and Junos OS Evolved: A malformed CFM packet or specific transit traffic leads to FPC crash
https://notcve.org/view.php?id=CVE-2024-39542
An Improper Validation of Syntactic Correctness of Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series with MPC10/11 or LC9600, MX304, and Junos OS Evolved on ACX Series and PTX Series allows an unauthenticated, network based attacker to cause a Denial-of-Service (DoS). This issue can occur in two scenarios: 1. If a device, which is configured with SFLOW and ECMP, receives specific valid transit traffic, which is subject to sampling, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. (This scenario is only applicable to PTX but not to ACX or MX.) 2. If a device receives a malformed CFM packet on an interface configured with CFM, the packetio process crashes, which in turn leads to an evo-aftman crash and causes the FPC to stop working until it is restarted. Please note that the CVSS score is for the formally more severe issue 1. The CVSS score for scenario 2. is: 6.5 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) This issue affects Junos OS: * All versions before 21.2R3-S4, * 21.4 versions before 21.4R2, * 22.2 versions before 22.2R3-S2; Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * 21.4 versions before 21.4R2-EVO. • https://supportportal.juniper.net/JSA83002 • CWE-1286: Improper Validation of Syntactic Correctness of Input •

https://notcve.org/view.php?id=CVE-2024-39538
A Buffer Copy without Checking Size of Input vulnerability in the PFE management daemon (evo-pfemand) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).When multicast traffic with a specific, valid (S,G) is received, evo-pfemand crashes which leads to an outage of the affected FPC until it is manually recovered. This issue affects Junos OS Evolved on ACX7000 Series: * 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-S3-EVO, * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO. • https://supportportal.juniper.net/JSA82998 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2024-39537
An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in Juniper Networks Junos OS Evolved on ACX 7000 Series allows an unauthenticated, network-based attacker to cause a limited information disclosure and availability impact to the device. Due to a wrong initialization, specific processes which should only be able to communicate internally within the device can be reached over the network via open ports. This issue affects Junos OS Evolved on ACX 7000 Series: * All versions before 21.4R3-S7-EVO, * 22.2-EVO versions before 22.2R3-S4-EVO, * 22.3-EVO versions before 22.3R3-S3-EVO, * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO. • https://supportportal.juniper.net/JSA82997 • CWE-923: Improper Restriction of Communication Channel to Intended Endpoints •

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: 8EXPL: 0CVE-2024-39531 – Junos OS Evolved: ACX 7000 Series: Protocol specific DDoS configuration affects other protocols
https://notcve.org/view.php?id=CVE-2024-39531
An Improper Handling of Values vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows a network-based, unauthenticated attacker to cause a Denial-of-Service (DoS). If a value is configured for DDoS bandwidth or burst parameters for any protocol in a queue, all protocols which share the same queue will have their bandwidth or burst value changed to the new value. If, for example, OSPF was configured with a certain bandwidth value, ISIS would also be limited to this value. So inadvertently either the control plane is open for a high level of specific traffic which was supposed to be limited to a lower value, or the limit for a certain protocol is so low that chances to succeed with a volumetric DoS attack are significantly increased. This issue affects Junos OS Evolved on ACX 7000 Series: * All versions before 21.4R3-S7-EVO, * 22.1 versions before 22.1R3-S6-EVO, * 22.2 versions before 22.2R3-S3-EVO, * 22.3 versions before 22.3R3-S3-EVO, * 22.4 versions before 22.4R3-S2-EVO, * 23.2 versions before 23.2R2-EVO, * 23.4 versions before 23.4R1-S1-EVO, 23.4R2-EVO. • https://supportportal.juniper.net/JSA82991 • CWE-229: Improper Handling of Values •
