CVE-2021-31354 – Junos OS and Junos OS Evolved: A vulnerability in the Juniper Agile License Client may allow an attacker to perform Remote Code Execution (RCE)
https://notcve.org/view.php?id=CVE-2021-31354
An Out Of Bounds (OOB) access vulnerability in the handling of responses by a Juniper Agile License (JAL) Client in Juniper Networks Junos OS and Junos OS Evolved, configured in Network Mode (to use Juniper Agile License Manager) may allow an attacker to cause a partial Denial of Service (DoS), or lead to remote code execution (RCE). The vulnerability exists in the packet parsing logic on the client that processes the response from the server using a custom protocol. An attacker with control of a JAL License Manager, or with access to the local broadcast domain, may be able to spoof a new JAL License Manager and/or craft a response to the Junos OS License Client, leading to exploitation of this vulnerability. This issue only affects Junos systems configured in Network Mode. Systems that are configured in Standalone Mode (the default mode of operation for all systems) are not vulnerable to this issue. • https://kb.juniper.net/JSA11219 • CWE-125: Out-of-bounds Read •
CVE-2021-31353 – Junos OS and Junos OS Evolved: RPD core upon receipt of specific BGP update
https://notcve.org/view.php?id=CVE-2021-31353
An Improper Handling of Exceptional Conditions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows an attacker to inject a specific BGP update, causing the routing protocol daemon (RPD) to crash and restart, leading to a Denial of Service (DoS). Continued receipt and processing of the BGP update will create a sustained Denial of Service (DoS) condition. This issue affects very specific versions of Juniper Networks Junos OS: 19.3R3-S2; 19.4R3-S3; 20.2 versions 20.2R2-S3 and later, prior to 20.2R3-S2; 20.3 versions 20.3R2 and later, prior to 20.3R3; 20.4 versions 20.4R2 and later, prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS 20.1 is not affected by this issue. This issue also affects Juniper Networks Junos OS Evolved: All versions prior to 20.4R2-S3-EVO, 20.4R3-EVO; 21.1-EVO versions prior to 21.1R2-EVO; 21.2-EVO versions prior to 21.2R2-EVO. • https://kb.juniper.net/JSA11218 • CWE-755: Improper Handling of Exceptional Conditions •
CVE-2021-0284 – Junos OS: Upon receipt of specific sequences of genuine packets destined to the device the kernel will crash and restart (vmcore)
https://notcve.org/view.php?id=CVE-2021-0284
A buffer overflow vulnerability in the TCP/IP stack of Juniper Networks Junos OS allows an attacker to send specific sequences of packets to the device thereby causing a Denial of Service (DoS). By repeatedly sending these sequences of packets to the device, an attacker can sustain the Denial of Service (DoS) condition. The device will abnormally shut down as a result of these sent packets. A potential indicator of compromise will be the following message in the log files: "eventd[13955]: SYSTEM_ABNORMAL_SHUTDOWN: System abnormally shut down" This issue is only triggered by traffic destined to the device. Transit traffic will not trigger this issue. • https://kb.juniper.net/JSA11200 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVE-2020-7656 – jquery: Cross-site scripting (XSS) via <script> HTML tags containing whitespaces
https://notcve.org/view.php?id=CVE-2020-7656
jquery prior to 1.9.0 allows Cross-site Scripting attacks via the load method. The load method fails to recognize and remove "<script>" HTML tags that contain a whitespace character, i.e: "</script >", which results in the enclosed script logic to be executed. jquery versiones anteriores a 1.9.0, permite ataques de tipo Cross-site Scripting por medio del método de carga. El método de carga presenta un fallo al reconocer y eliminar las etiquetas HTML "(script)" que contienen un carácter de espacio en blanco, es decir: "(/script )", lo cual resulta en que la lógica de script adjunta sea ejecutada. A flaw was found in jquery in versions prior to 1.9.0. A cross-site scripting attack is possible as the load method fails to recognize and remove "<script>" HTML tags that contain a whitespace character which results in the enclosed script logic to be executed. • https://github.com/ossf-cve-benchmark/CVE-2020-7656 https://security.netapp.com/advisory/ntap-20200528-0001 https://snyk.io/vuln/SNYK-JS-JQUERY-569619 https://supportportal.juniper.net/s/article/2021-07-Security-Bulletin-Junos-OS-Multiple-J-Web-vulnerabilities-resolved-in-Junos-OS-21-2R1?language=en_US https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2020-7656 https://bugzilla.redhat.com/show_bug.cgi?id=1850119 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
