Description

Soko if the code that powers packages.gentoo.org. Prior to version 1.0.2, the two package search handlers, `Search` and `SearchFeed`, implemented in `pkg/app/handler/packages/search.go`, are affected by a SQL injection via the `q` parameter. As a result, unauthenticated attackers can execute arbitrary SQL queries on `https://packages.gentoo.org/`. It was also demonstrated that primitive was enough to gain code execution in the context of the PostgreSQL container. The issue was addressed in commit `4fa6e4b619c0362728955b6ec56eab0e0cbf1e23y` of version 1.0.2 using prepared statements to interpolate user-controlled data in SQL queries.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
