Vulnerability from github – Published: 2026-03-04 18:29 – Updated: 2026-03-05 22:29Impact
There is a potential vulnerability in Traefik managing TLS handshake on TCP routers.
When Traefik processes a TLS connection on a TCP router, the read deadline used to bound protocol sniffing is cleared before the TLS handshake is completed. When a TLS handshake read error occurs, the code attempts a second handshake with different connection parameters, silently ignoring the initial error. A remote unauthenticated client can exploit this by sending an incomplete TLS record and stopping further data transmission, causing the TLS handshake to stall indefinitely and holding connections open.
By opening many such stalled connections in parallel, an attacker can exhaust file descriptors and goroutines, degrading availability of all services on the affected entrypoint.

If there are any questions or comments about this advisory, please open an issue.
Original Description Traefik's TCP router uses a connection-level read deadline to bound protocol sniffing (peeking a TLS client hello), but then clears the deadline via conn.SetDeadline(time.Time{}) before delegating the connection to TLS forwarding. A remote unauthenticated client can send an incomplete TLS record header and stop sending data. After the initial peek times out, the router clears the deadline and the subsequent TLS handshake reads can stall indefinitely, holding connections open and consuming resources. ### Expected vs Actual Expected: if an entrypoint-level read deadline is used to bound initial protocol sniffing, TLS handshake reads should remain bounded by a deadline (either the same deadline is preserved, or a dedicated handshake timeout is enforced). Actual: after protocol sniffing the router clears the connection deadline and delegates to TLS handling; an attacker can keep the TLS handshake stalled beyond the configured read timeout. ### Severity HIGH CWE: CWE-400 (Uncontrolled Resource Consumption) ### Affected Code - pkg/server/router/tcp/router.go: (*Router).ServeTCP clears the deadline before TLS forwarding - conn.SetDeadline(time.Time{}) removes the entrypoint-level deadline that previously bounded reads ### Root Cause In (*Router).ServeTCP, after sniffing a TLS client hello, the router removes the connection read deadline: // Remove read/write deadline and delegate this to underlying TCP server // (for now only handled by HTTP Server) if err := conn.SetDeadline(time.Time{}); err != nil { ... } TLS handshake reads that happen after this point are not guaranteed to have any deadline, so a client that stops sending bytes can keep the connection open indefinitely. ### Attacker Control Attacker-controlled input is the raw TCP byte stream on an entrypoint that routes to a TLS forwarder. The attacker controls: 1. Sending a partial TLS record header (enough to trigger the TLS sniffing path) 2. Stopping further sends so the subsequent handshake read blocks ### Impact Each stalled connection occupies file descriptors and goroutines (and may consume additional memory depending on buffering). By opening many such connections in parallel, an attacker can cause resource exhaustion and degrade availability. ### Reproduction Attachments include poc.zip with a self-contained integration harness. It pins the repository commit, applies fix.patch as the control variant, and runs a regression-style test that demonstrates the stall in canonical mode and the timeout in control mode. Run canonical (vulnerable): unzip poc.zip -d poc cd poc make test Canonical output excerpt: PROOF_MARKER Run control (deadline preserved / no stall): unzip poc.zip -d poc cd poc make control Control output excerpt: NC_MARKER ### Recommended Fix Do not clear the entrypoint-level deadline prior to completing TLS handshake, or enforce a dedicated handshake timeout for the TLS forwarder path. Fix accepted when: an incomplete TLS record cannot stall past the configured entrypoint-level read deadline (or an explicit handshake timeout), and a regression test covers the canonical/control behavior.

Vulnerability from github – Published: 2022-05-24 17:31 – Updated: 2023-08-16 18:30A vulnerability in the SSL VPN negotiation process for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient direct memory access (DMA) memory management during the negotiation phase of an SSL VPN connection. An attacker could exploit this vulnerability by sending a steady stream of crafted Datagram TLS (DTLS) traffic to an affected device. A successful exploit could allow the attacker to exhaust DMA memory on the device and cause a DoS condition.

This could allow traffic to be forwarded to the NX-OS CPU for processing, leading to high CPU utilization and a denial of service (DoS) condition. The vulnerability is due to a bad code fix in the 7.3.2 code train that could allow traffic to the management interface to be misclassified and not match the proper configured ACLs. An attacker could exploit this vulnerability by sending crafted traffic to the management interface. An exploit could allow the attacker to bypass the configured management interface ACLs and impact the CPU of the targeted device, resulting in a DoS condition.

Mitigation
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
