Description

Requests Session object does not verify requests after making first request with verify=False

When using a requests.Session, if the first request to a given origin is made with verify=False, TLS certificate verification may remain disabled for all subsequent requests to that origin, even if verify=True is explicitly specified later.

This occurs because the underlying connection is reused from the session's connection pool, causing the initial TLS verification setting to persist for the lifetime of the pooled connection. As a result, applications may unintentionally send requests without certificate verification, leading to potential man-in-the-middle attacks and compromised confidentiality or integrity.

This behavior affects versions of requests prior to 2.32.0.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is high, an attacker needs administrative privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:N

  • Attack vector: Local — a local account, shell or session on the host is needed.
  • Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
  • Privileges required: High — administrative rights are needed first.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: None.

Weakness class

CVE-2024-35195 is classified as CWE-670: Always-Incorrect Control Flow Implementation. The control flow does not do what the logic intends, so a check never has the effect it appears to have.
