CVE-2020-10803

In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was discovered where malicious code could be used to trigger an XSS attack through retrieving and displaying results (in tbl_get_field.php and libraries/classes/Display/Results.php). The attacker must be able to insert crafted data into certain database tables, which when retrieved (for instance, through the Browse tab) can trigger the XSS attack.

5.4 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.

Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
