Fixing SymPy’s Limit Calculator Flaw

SymPy is a Python library written entirely in python that aims to become a full-featured computer algebra system (CAS) while keeping it’s code as simple as possible.
If you ever have to do advanced math things with Python i’d highly recommend SymPy. It’s capable of solving equations, plotting graphs, taking integrals and most other math’y things you can think of.
A limit is the value that a function “approaches” as the input(x value) “approaches” some value. For example, the limit of x/x as x approaches zero would be written as follows

Critical Cisco Flaw Fixed in Data Center Network Manager

The flaw could allow a remote, unauthenticated attacker to bypass authentication on vulnerable devices.

Cisco is warning of several critical and high-severity flaws in its Data Center Network Manager (DCNM) for managing network platforms and switches.

DCNM is a platform for managing Cisco data centers that run Cisco’s NX-OS — the network operating system used by Cisco’s Nexus-series Ethernet switches and MDS-series Fibre Channel storage area network switches. The flaws exist in the REST API of DCNM — and the most serious of these could allow an unauthenticated, remote attacker to bypass authentication, and ultimately execute arbitrary actions with administrative privileges on a vulnerable device.

The critical flaw (CVE-2020-3382), which was found during internal security testing, rates 9.8 out of 10 on the CVSS scale, making it critical in severity. While the flaw is serious, the Cisco Product Security Incident Response Team said it is not aware of any public announcements or malicious exploits of the vulnerability.

“The vulnerability exists because different installations share a static encryption key,” said Cisco, in a security update on Wednesday. “An attacker could exploit this vulnerability by using the static key to craft a valid session token. A successful exploit could allow the attacker to perform arbitrary actions through the REST API with administrative privileges.”

This vulnerability affects all deployment modes of all Cisco DCNM appliances that were installed using .ova or .iso installers, and affects Cisco DCNM software releases 11.0(1), 11.1(1), 11.2(1), and 11.3(1).

“Cisco has confirmed that this vulnerability does not affect Cisco DCNM instances that were installed on customer-provided operating systems using the DCNM installer for Windows or Linux,” said Cisco. “Cisco has also confirmed that this vulnerability does not affect Cisco DCNM software releases 7.x and 10.x.”

Cisco has released software updates that address the vulnerability, though there are no workarounds that address the flaw.

Cisco also patched five high-severity flaws in DCNM, including two command-injection flaws (CVE-2020-3377 and CVE-2020-3384 ) that could allow an authenticated, remote attacker to inject arbitrary commands on affected devices; a path traversal issue (CVE-2020-3383) that could enable an authenticated, remote attacker to conduct directory traversal attacks on vulnerable devices; an improper authorization flaw (CVE-2020-3386), allowing an authenticated, remote attacker with a low-privileged account to bypass authorization on the API of an affected device; and an authentication bypass glitch (CVE-2020-3376) allowing an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions on an affected device.

DCNM came in the spotlight earlier this year when three critical vulnerabilities (CVE-2019-15975, CVE-2019-15976, CVE-2019-15977) were discovered in the tool in January. Two critical flaws were also found last year in DCNM, which could allow attackers to take control of impacted systems.

Cisco on Wednesday also patched a critical vulnerability (CVE-2020-3374) in the web-based management interface of its SD-WAN vManage Network Management system (the centralized management platform). This flaw could allow a remote attacker to bypass authorization, enabling them to access sensitive information, modify the system configuration, or impact the availability of the affected system – but the attacker would need to be authenticated to exploit the flaw.

Critical Intel Flaw Afflicts Several Motherboards, Server Systems, Compute Modules

Intel is warning of a rare critical-severity vulnerability affecting several of its motherboards, server systems and compute modules. The flaw could allow an unauthenticated, remote attacker to achieve escalated privileges.

The recently patched flaw (CVE-2020-8708) ranks 9.6 out of 10 on the CVSS scale, making it critical. Dmytro Oleksiuk, who discovered the flaw, told Threatpost that it exists in the firmware of Emulex Pilot 3. This baseboard-management controller is a service processor that monitors the physical state of a computer, network server or other hardware devices via specialized sensors.

Emulex Pilot 3 is used by various motherboards, which aggregate all the server components into one system. Also impacted are various server operating systems, and some Intel compute modules, which are electronic circuits, packaged onto a circuit board, that provide various functions.

The critical flaw stems from improper-authentication mechanisms in these Intel products before version 1.59.

In bypassing authentication, an attacker would be able to access to the KVM console of the server. The KVM console can access the system consoles of network devices to monitor and control their functionality. The KVM console is like a remote desktop implemented in the baseboard management controller – it provides an access point to the display, keyboard and mouse of the remote server, Oleksiuk told Threatpost.

The flaw is dangerous as it’s remotely exploitable, and attackers don’t need to be authenticated to exploit it – though they need to be located in the same network segment as the vulnerable server, Oleksiuk told Threatpost.

“The exploit is quite simple and very reliable because it’s a design flaw,” Oleksiuk told Threatpost.

Beyond this critical flaw, Intel also fixed bugs tied to 22 critical-, high-, medium- and low-severity CVEs affecting its server board, systems and compute modules. Other high-severity flaws include a heap-based overflow (CVE-2020-8730) that’s exploitable as an authenticated user; incorrect execution-assigned permissions in the file system (CVE-2020-8731); and a buffer overflow in daemon (CVE-2020-8707) — all three of which enable escalated privileges.

Oleksiuk was credited with reporting CVE-2020-8708, as well as CVE-2020-8706, CVE-2020-8707. All other CVEs were found internally by Intel.

Affected server systems include: The R1000WT and R2000WT families, R1000SP, LSVRP and LR1304SP families and R1000WF and R2000WF families.

Impacted motherboards include: The S2600WT family, S2600CW family, S2600KP family, S2600TP family, S1200SP family, S2600WF family, S2600ST family and S2600BP family.

Finally, impacted compute modules include: The HNS2600KP family, HNS2600TP family and HNS2600BP family. More information regarding patches is available in Intel’s security advisory.

Intel also issued an array of other security advisories addressing high-severity flaws across its product lines, including ones that affect Intel Graphics Drivers, Intel’s RAID web console 3 for Windows, Intel Server Board M10JNP2SB and Intel NUCs.
