Summary:Archer contains fixes for multiple security vulnerabilities that could potentially be exploited by malicious users to compromise the affected system.
Details:

Archer has been updated for the following vulnerabilities: 

 

• Open Redirect Vulnerability – CVE-2020-29537

 

Archer before 6.8 P2 (6.8.0.2) is affected by an open redirect vulnerability. A remote privileged attacker may potentially redirect legitimate users to arbitrary web sites and conduct phishing attacks. The attacker could then steal the victims’ credentials and silently authenticate them to the Archer application without the victims realizing an attack occurred.


CVSSv3.1 Base Score: 4.6 (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N)


• Insecure Cryptographic Storage Vulnerability – CVE-2020- 29536
Archer before 6.8 P2 (6.8.0.2) is affected by a path exposure vulnerability. A remote authenticated malicious attacker with access to service files may obtain sensitive information to use it in further attacks.


CVSSv3.1 Base Score: 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)


• Cross-site Scripting Vulnerability – CVE-2020- 29535
Archer before 6.8 P4 (6.8.0.4) contains a stored XSS vulnerability. A remote authenticated malicious Archer user could potentially exploit this vulnerability to store malicious HTML or JavaScript code in a trusted application data store. When application users access the corrupted data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application.


CVSSv3 Base Score: 5.3 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N)


• Improper Access Control Vulnerability – CVE-2020- 29538
Archer before 6.9 P1 (6.9.0.1) contains an improper access control vulnerability on an API. A remote authenticated malicious administrative user can potentially exploit this vulnerability to gather information about the system and may use this information in subsequent attacks.


CVSSv3 Base Score: 4.9 (AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N)
