Security Vulnerabilities - CVEs Published In May 2021
Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters. An authenticated remote SMTP client can insert newline characters into a spool file (which indirectly leads to remote code execution as root) via AUTH= in a MAIL FROM command.

Exim 4 before 4.94.2 allows Buffer Underwrite that may result in unauthenticated remote attackers executing arbitrary commands, because smtp_ungetc was only intended to push back characters, but can actually push back non-character error codes such as EOF.

Exim 4 before 4.94.2 allows Out-of-bounds Read because pdkim_finish_bodyhash does not validate the relationship between sig->bodyhash.len and b->bh.len; thus, a crafted DKIM-Signature header might lead to a leak of sensitive information from process memory.

Exim 4 before 4.94.2 has Improper Neutralization of Line Delimiters, relevant in non-default configurations that enable Delivery Status Notification (DSN). Certain uses of ORCPT= can place a newline into a spool header file, and indirectly allow unauthenticated remote attackers to execute arbitrary commands as root.

Multiple vulnerabilities in Cisco SD-WAN vManage Software could allow an unauthenticated, remote attacker to execute arbitrary code or gain access to sensitive information, or allow an authenticated, local attacker to gain escalated privileges or gain unauthorized access to the application. For more information about these vulnerabilities, see the Details section of this advisory.

A vulnerability in the web-based messaging service interface of Cisco SD-WAN vManage Software could allow an unauthenticated, adjacent attacker to bypass authentication and authorization and modify the configuration of an affected system. To exploit this vulnerability, the attacker must be able to access an associated Cisco SD-WAN vEdge device. This vulnerability is due to insufficient authorization checks. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based messaging service interface of an affected system. A successful exploit could allow the attacker to gain unauthenticated read and write access to the affected vManage system. With this access, the attacker could access information about the affected vManage system, modify the configuration of the system, or make configuration changes to devices that are managed by the system.

Multiple vulnerabilities in the web-based management interface of Cisco Unified Communications Manager IM & Presence Service could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. These vulnerabilities are due to improper validation of user-submitted parameters. An attacker could exploit these vulnerabilities by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain data or modify data that is stored in the underlying database.
