Sugarcrm: Improper Neutralization of Special Elements in Output Used by a Downstream Component

CVE-2023-35810 is a high-severity improper neutralization of special elements in output used by a downstream component vulnerability in Sugarcrm, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 11.0.6, 12.0.3 as the first without the flaw, so updating Sugarcrm to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.22% chance of exploitation within 30 days, higher than 69% of scored CVEs.

Official description

An issue was discovered in SugarCRM Enterprise before 11.0.6 and 12.x before 12.0.3. A Second-Order PHP Object Injection vulnerability has been identified in the DocuSign module. By using crafted requests, custom PHP code can be injected and executed through the DocuSign module because of missing input validation. Admin user privileges are required to exploit this vulnerability. Editions other than Enterprise are also affected.

The underlying weakness: Improper Neutralization of Special Elements in Output Used by a Downstream Component

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

How developers prevent this class of flaw

  • Programming languages and supporting technologies might be chosen which are not subject to these issues.
  • Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
